This study focuses on the Ki lo Degree Survey (KiDS) as the primary dataset. Initially\, the model was trained on simulated data from the Bologna Lens Challenge\, designed to cl osely mimic actual KiDS observations. Following this\, the model was refin ed through fine-tuning and data augmentation using real KiDS data\, which included images of previously identified SGL candidates and non-lens examp les. This refinement led to a substantial 70% reduction in false positives \, although the precision remained lower than 1%.\nThis approach resulted in a catalog of 263 SGL candidates\, of which 43 are newly discovered high -confidence SGLs. This seminar will highlight the difficulties in detectin g rare objects such as gravitational lenses and the challenges to overcome to be ready for the next generation of wide-area surveys.\n\nhttps://even ts.ncbj.gov.pl/event/300/contributions/1556/ LOCATION:NCBJ Room 207 URL:https://events.ncbj.gov.pl/event/300/contributions/1556/ END:VEVENT BEGIN:VEVENT SUMMARY:Search for Exotics in B decays at LHCb DTSTART;VALUE=DATE-TIME:20240613T071500Z DTEND;VALUE=DATE-TIME:20240613T081500Z DTSTAMP;VALUE=DATE-TIME:20260305T082036Z UID:indico-contribution-300-1561@events.ncbj.gov.pl DESCRIPTION:Speakers: Salil Joshi (NCBJ)\nOut of all the unexpected partic les discovered in the past two decades\, about 30 observed exotic hadrons candidates\, i.e. ones that do not fit into the paradigms of either bosoni c or fermionic baryons\, have masses in the same region as conventional ch armonium states (charmonium-like) or bottomonium-like. For these enigmatic exotic hadrons observed to date\, no scientific consensus has yet emerged to explain all of them and their formation\, properties\, structure by me ans of a single\, universal theoretical principle. It is this pattern of o ne unexpected result after another\, with the emergence of desperately few connections\, that has characterized the last 20 years of experimental st udies in this field. This presentation is aimed at briefly introducing thi s rapidly expanding field of QCD exotica and take a guided tour through th e process of finding new exotics in B meson decays in data collected at LH Cb experiment in the last 12 years.\n\nhttps://events.ncbj.gov.pl/event/30 0/contributions/1561/ LOCATION:NCBJ Room 207 URL:https://events.ncbj.gov.pl/event/300/contributions/1561/ END:VEVENT BEGIN:VEVENT SUMMARY:Study of direct photon production in Pb-Pb collisions at √sNN = 5.02 TeV with ALICE experiment’s Photon Spectrometer (PHOS) at Large Had ron Collider DTSTART;VALUE=DATE-TIME:20240509T071500Z DTEND;VALUE=DATE-TIME:20240509T081500Z DTSTAMP;VALUE=DATE-TIME:20260305T082036Z UID:indico-contribution-300-1517@events.ncbj.gov.pl DESCRIPTION:Speakers: Sushobhan Mandal ()\nThe Quark-Gluon Plasma (QGP)\, comprising deconfined quarks and gluons\, is believed to have existed in t he Universe shortly after the Big Bang. As the QGP cools\, it transitions into the hadronic matter that we observe today. In laboratory settings\, s mall-scale "Big Bangs" are artificially created through high-energy heavy- ion collisions\, which heat the hadronic matter above the transition tempe rature\, approximately 150 MeV\, leading to the formation of the QGP. Dire ct photons serve as unique probes in high-energy proton-proton and nucleus -nucleus collisions\, interacting weakly with the dense and hot quark-gluo n medium formed during these events. These photons escape freely\, providi ng undistorted information about the collision's evolution. In the Photon Spectrometer of the ALICE experiment at the Large Hadron Collider at CERN \, photons\, originating from the collisions of lead nuclei at energy √ sNN = 5.02 TeV \, are measured with very high precision. By disentangling the contributions of decay\, prompt and thermal photons emitted during the se collisions\, we can estimate the effects of cold and hot nuclear matter and gain insights into the temperature\, correlations\, and collective ph enomena within the QGP.\n\nhttps://events.ncbj.gov.pl/event/300/contributi ons/1517/ LOCATION:NCBJ Room 207 URL:https://events.ncbj.gov.pl/event/300/contributions/1517/ END:VEVENT BEGIN:VEVENT SUMMARY:Redshift Evolution of Lensing Galaxy Density Slopes via Model-Inde pendent Distance Ratios DTSTART;VALUE=DATE-TIME:20240418T071500Z DTEND;VALUE=DATE-TIME:20240418T081500Z DTSTAMP;VALUE=DATE-TIME:20260305T082036Z UID:indico-contribution-300-1478@events.ncbj.gov.pl DESCRIPTION:Speakers: Shuaibo Geng (National Center for Nuclear Research)\ nStrong lensing (SL) systems\, which are expected to be massively discover ed by the LSST\, provide powerful tool for studying cosmology and galaxy s tructure. The Einstein radius is a robust measure of the total projected m ass of the lens. When combined with stellar kinematics it can be used to c onstrain the radial mass profiles of the lens. However\, the observed angu lar size of the Einstein radius depends also on the cosmological model thr ough the distance ratio D_ls/D_s. Hence\, galaxy structure and cosmology b ecome entangled.\nTherefore\, if one needs to use strong lenses for testin g cosmological model one needs to assume the effective model of the lens m ass distribution. Usually this is SIS or more general spherically symmetri c power-law (PL) model. On the other hand\, PL slope parameter γ is being determined from observations assuming a fiducial cosmological model (usua lly vanilla LCDM model). This creates a vicious circle. In this study\, us ing a compilation of 161 well studied SL systems we attempted at character izing the PL slope and its possible evolution with redshift using an origi nal cosmological model independent approach. Namely\, the distance ratios have been reconstructed using non-parametric regression methods\, specific ally Artificial Neural Networks (ANN) and Gaussian Processes (GP)\, applie d to the data comprising the Hubble parameter H(z) from cosmic chronometer s and luminosity distances D_L(z) from type Ia supernovae. Such reconstruc tion relates only to what the nature tells us in the data\, without assumi ng any specific cosmological model.\nWe tested two approaches regarding th e lens mass distribution: The first is with a single PL index characterizi ng the total mass (both dark and luminous). The second one distinguishes γ PL index as describing the total mass ρ{tot}(r)= ρ{tot} r^{-γ} and δ PL index describing luminous matter ρ{lum}(r)= ρ{lum} r^{-δ}. Across various methods\, our results show that the total mass becomes more conce ntrated from redshift z~1 to the present day. In models where the density slope of luminous matter can be different from that of the total mass\, we find that the density profile of luminous matter flattens over time. And this model suggests a steeper density slope for luminous mass relative to total mass\, consistent with observations from detailed lensing galaxy stu dies. These findings offer a reference point for leveraging strong lensing systems in cosmological constraints and studying galaxy evolution\, with potential applications currently being explored.\n\nhttps://events.ncbj.go v.pl/event/300/contributions/1478/ LOCATION:NCBJ Room 207 URL:https://events.ncbj.gov.pl/event/300/contributions/1478/ END:VEVENT BEGIN:VEVENT SUMMARY:Exploring the Low Surface Brightness Galaxies in Abell 194 with T ransfer Learning.

The upcoming large-scale surveys such as the Rubin Observatory Legacy Survey of Space and Time (LSST) and Euclid are ex pected to uncover a large number of LSBGs which would require accurate au tomated methods for their detection. We study the scope of transfer learni ng for the identification of LSBGs in the Abell 194 cluster with the deep data we obtained from our Hyper Suprime-Cam (HSC) observations of this clu ster. We use two ensemble of transformer models that have been trained on the dark energy survey data release 1 (DES DR 1) which is two order of mag nitude shallower than the data from HSC. The transformer ensemble model a chieved a classification accuracy of 95% on the data from DES DR1 and ach ieved a recall rate of 93% on the HSC dataset. Using the transformer ensem ble models we identify a sample of 171 LSBGs among which 87 are completely new from the cluster Abell 194. We further classify 28 LSBGs among them a s ultra-diffuse galaxies (UDGs). We show that transfer learning from a sha llow survey to a deeper survey using transformer models can be successful with appropriate data normalization. This methodology could prove valuable for identifying and analyzing astronomical data in upcoming surveys like LSST and Euclid.\n\nhttps://events.ncbj.gov.pl/event/300/contributions/147 9/ LOCATION:NCBJ Room 207 URL:https://events.ncbj.gov.pl/event/300/contributions/1479/ END:VEVENT BEGIN:VEVENT SUMMARY:Asymptotic Safety and the Litim Sannino Model DTSTART;VALUE=DATE-TIME:20240411T071500Z DTEND;VALUE=DATE-TIME:20240411T081500Z DTSTAMP;VALUE=DATE-TIME:20260305T082036Z UID:indico-contribution-300-1472@events.ncbj.gov.pl DESCRIPTION:Speakers: Daniele Rizzo (National Center for Nuclear Research (NCBJ)\, Warsaw\, Poland)\nWhen studying the running of coupling constants in some theories - including the Standard Model of particle physics - we may find that perturbation theory cannot be used to describe the theory fo r very low or very high energy scales. The assumption of an ultra-violet ( UV) interacting Fixed Point (FP) can preserve the theory from running into infinity. This solution is called Asymptotic Safety (AS). I will present a toy model of non-abelian gauge fields and quarks in the large Nc limit a nd show how the theory at the UV FP is described by only one (small and po sitive) real parameter\, so that all the interesting quantities are polyno mials in such parameter. I will present both a perturbative and a non-pert urbative analysis of the UV FP and discuss the validity of the assumption of AS as a function of the single parameter of the theory.\n\nhttps://even ts.ncbj.gov.pl/event/300/contributions/1472/ LOCATION:NCBJ Room 207 URL:https://events.ncbj.gov.pl/event/300/contributions/1472/ END:VEVENT BEGIN:VEVENT SUMMARY:(1+1) dimensional Quantum Gravity from the Corner Proposal DTSTART;VALUE=DATE-TIME:20240404T071500Z DTEND;VALUE=DATE-TIME:20240404T081500Z DTSTAMP;VALUE=DATE-TIME:20260305T082036Z UID:indico-contribution-300-1471@events.ncbj.gov.pl DESCRIPTION:Speakers: Ludovic Varrin ()\nThe concept of symmetries is cruc ial in our comprehension of modern theoretical physics. The Corner Proposa l introduces a novel framework where symmetries are reinstated as foundati onal principles in our understanding of gravity. This aims to describe gra vity using a language that is more adapted to quantization. In this presen tation\, I will provide an overview of the essential tools required to gra sp the conceptual framework of the proposal\, accompanied by simple exampl es for illustration. Subsequently\, I will present elements of our recent research applying the proposal to the case of 1+1 dimensional gravity. Fin ally\, I will demonstrate the framework's utility by calculating the entan glement entropy between two spatial regions—a significant challenge in q uantum gravity. The result is the 1+1 dimensional equivalent of the well-e stablished Bekenstein-Hawking area law governing the entropy of gravitatio nal systems.\n\nhttps://events.ncbj.gov.pl/event/300/contributions/1471/ LOCATION:NCBJ Room 207 URL:https://events.ncbj.gov.pl/event/300/contributions/1471/ END:VEVENT BEGIN:VEVENT SUMMARY:An introduction to search for vector boson scattering production o f same sign W boson decaying to muons with pp collisions at sqrt(s) = 13.6 TeV collected by the CMS experiment DTSTART;VALUE=DATE-TIME:20240321T081500Z DTEND;VALUE=DATE-TIME:20240321T091500Z DTSTAMP;VALUE=DATE-TIME:20260305T082036Z UID:indico-contribution-300-1453@events.ncbj.gov.pl DESCRIPTION:Speakers: Mohammad Mousavi ()\nIn this presentation I will giv e an introduction to vector boson scattering processes at LHC. I aimed sca ttering two same sign W bosons leading to two same sign muons in associati on with two jets. To identify the muons among many other muons coming from other processes in the CMS experiment\, we define a signal region with re quiring two jets with large pseudorapidity separation and high invariant m ass. Moreover\, we first are required to identify all backgrounds contribu ting in our aimed analysis\, then we measure their contribution in signal region so that we can measure signal events by subtraction all backgrounds from observed events in the signal region. There are two kinds of backgro und in my analysis\, one of which is non-prompt background. Non-prompt bac kgrounds are measured directly from data by a so-called data-driven method . Other backgrounds can be estimated with MC simulation.\n\nhttps://events .ncbj.gov.pl/event/300/contributions/1453/ LOCATION:NCBJ Room 207 URL:https://events.ncbj.gov.pl/event/300/contributions/1453/ END:VEVENT BEGIN:VEVENT SUMMARY:Tau neutrino appearance and the measurement of neutrino mass order ing in the flux of atmospheric neutrinos at Super-Kamiokande DTSTART;VALUE=DATE-TIME:20240314T081500Z DTEND;VALUE=DATE-TIME:20240314T091500Z DTSTAMP;VALUE=DATE-TIME:20260305T082036Z UID:indico-contribution-300-1452@events.ncbj.gov.pl DESCRIPTION:Speakers: Maitrayee Mandal ()\nElectron and muon neutrinos are produced in the atmosphere by cosmic rays\, and neutrino oscillations in the atmospheric flux lead to the production of tau neutrinos. Since 1996\, Super-Kamiokande (SK) has been collecting data on atmospheric neutrinos\, with an energy threshold for the detection of tau neutrinos set at 3.5 Ge V. In the same energy range\, matter effects give rise to a resonance of e lectron neutrinos or anti-neutrinos\, depending on whether the neutrino ma ss-ordering is normal or inverted. Thus\, SK can unveil the neutrino mass- ordering contingent on reducing the tau neutrino background. We present th e latest measurement of tau neutrino appearance at SK and potential enhanc ements to the experiment's sensitivity to neutrino mass-ordering by constr aining tau neutrinos with a neural network.\n\nhttps://events.ncbj.gov.pl/ event/300/contributions/1452/ LOCATION:NCBJ Room 207 URL:https://events.ncbj.gov.pl/event/300/contributions/1452/ END:VEVENT BEGIN:VEVENT SUMMARY:Shedding light onto the dark freeze-out with FIMPs DTSTART;VALUE=DATE-TIME:20240307T081500Z DTEND;VALUE=DATE-TIME:20240307T091500Z DTSTAMP;VALUE=DATE-TIME:20260305T082036Z UID:indico-contribution-300-1437@events.ncbj.gov.pl DESCRIPTION:Speakers: Juan Esau Cervantes Hernandez (NCBJ Warsaw)\nIn this presentation\, I will discuss the concept of "Self Interacting Dark Matte r\," a hypothesis positing that the observed abundance of DM can be elucid ated through a secluded dark sector engaging in self-number changing react ions. Additionally\, I will introduce the freeze-in mechanism\, relying on feeble couplings between the Standard Model (SM) and the dark sector.

These components are thought to be exclusively linked to the process of star-formation\, implying that the molecular gas and dust should tightly follow each other’s fate. However\, the recent a dvent of the most powerful ground-based and space-based instruments such a s the Atacama Large Millimeter/submillimeter Array (ALMA) and the James We bb Space Telescope (JWST)\, is providing strong evidence that even galaxie s that stopped forming new stars millions\, or even billions\, of years ag o (called quiescent galaxies or QGs)\, contain significant amounts of dust with respect to their stellar mass.\n\nTo overcome the observational chal lenges (mostly due to the significant observing time required to measure d ust in QGs)\, we studied these objects in the state-of-the-art cosmologica l simulation SIMBA. In this talk\, I present the main results of my work with SIMBA: the pathways for dust and cold gas in QGs up to z=2. During t he talk I will show\, for the first time\, how different mechanisms\, both internal and environmental\, can affect the dust content after the cessat ion of the star formation. I will highlight how SIMBA predicts copious amo unts of dust in QGs at high-redshifts\, and paints a scenario in which que nching timescales and environments provide only a partial contribution to the evolutionary pathways of the ISM. I will finally explain the main resu lt of my finding: a key new channel for dust re-formation in QGs. This inv olves a prolonged dust growth in the ISM\, which activates almost independ ently from the evolution of the molecular hydrogen gas\, presenting new ex citing predictions for future observers.\n\nhttps://events.ncbj.gov.pl/eve nt/300/contributions/1436/ LOCATION:NCBJ Room 207 URL:https://events.ncbj.gov.pl/event/300/contributions/1436/ END:VEVENT BEGIN:VEVENT SUMMARY:Spin-entanglement in hyperon decays DTSTART;VALUE=DATE-TIME:20240125T090000Z DTEND;VALUE=DATE-TIME:20240125T100000Z DTSTAMP;VALUE=DATE-TIME:20260305T082036Z UID:indico-contribution-300-1424@events.ncbj.gov.pl DESCRIPTION:Speakers: Nora Salone ()\nRecent results published by the BESI II collaboration revealed a substantial update in the value of the Lambda baryon decay parameter.\nThis development is taken as the starting point f or a feasibility study of CP violation tests in strange baryon decays at n ext-generation J/Psi factories. The proposed formalism allows for directly comparing particle and antiparticle properties\, analyzing the weight of spin-correlation and polarization terms on such tests. \nFurthermore\, the spin-entanglement feature of the produced Yanti-Y pair can also be exploi ted to provide a description for hyperon semileptonic decays.

The bend ing of light by massive objects is a prediction of General Relativity and this phenomenon known as gravitational lensing has now become an indispen sable tool in astrophysics. Therefore\, in this era of astronomy\, the nex t most anticipated event is the detection of gravitational waves lensed by massive sources along the line of sight. \n\nThe lensed gravitational wav es has many applications such as detection of Intermediate Mass BlackHoles (IMBH)\, Primordial Black Holes\, precision cosmology etc. However\, all these application needs proper modelling of lensed gravitational waveform.

The Color Glas s Condensate (CGC) effective theory has been developed and used to study h igh-energy proton-nucleus collisions in particular. One of the main approx imations adopted in the Color Glass Condensate is the so-called eikonal ap proximation\, which amounts to neglecting power-suppressed corrections in the high-energy limit. This approximation is well justified for asymptotic ally high energies. However\, corrections to it might be sizable in practi ce\, in particular at the Relativistic Heavy Ion Collider and the upcoming Electron-Ion Collider. Therefore\, we need to bring precision in theory t o analyze the upcoming data from the colliders. For this\, we have to comp ute observables like scattering cross sections beyond the leading order of energy. Single-inclusive particle production is one of the promising chan nels to study CGC beyond eikonal order.\n\n In my talk\, I will briefly re view the eikonal approximation and how to go beyond eikonal order.

In my presentation\, I will discuss the implementation of various models of light dark matter within FORESEE\, providing insights into how experiments at the Forward Physics F acility at CERN can probe these models.\n\nhttps://events.ncbj.gov.pl/even t/300/contributions/1417/ LOCATION:NCBJ Room 207 URL:https://events.ncbj.gov.pl/event/300/contributions/1417/ END:VEVENT BEGIN:VEVENT SUMMARY:Galactic foreground bias in CMB lensing reconstruction DTSTART;VALUE=DATE-TIME:20231116T081500Z DTEND;VALUE=DATE-TIME:20231116T091500Z DTSTAMP;VALUE=DATE-TIME:20260305T082036Z UID:indico-contribution-300-1416@events.ncbj.gov.pl DESCRIPTION:Speakers: Kishan Deka (NCBJ)\nCosmic Microwave Background (CMB ) photons experience weak gravitational lensing by the large-scale structu re of the Universe along their journey. The weak lensing remaps the primor dial anisotropies of CMB temperature and polarisation\, contaminating the measurements of primordial fluctuations. Estimating the lensing potential field and delensing the CMB maps from recent and upcoming surveys are cruc ial tasks to improve cosmological measurements. However\, one of the main obstacles to these tasks is the presence of foreground contamination from our own galaxy.\n\nIn my talk\, I will give a overview of CMB polarisation \, CMB weak lensing and Galactic foreground emission\, followed by my resu lts on foreground contamination in reconstructing the lensing potential fi eld.\n\nhttps://events.ncbj.gov.pl/event/300/contributions/1416/ LOCATION:NCBJ Room 207 URL:https://events.ncbj.gov.pl/event/300/contributions/1416/ END:VEVENT BEGIN:VEVENT SUMMARY:Establishment of best practices in reducing the uncertainty of neu tron cross-sections with Bayesian methods DTSTART;VALUE=DATE-TIME:20231109T081500Z DTEND;VALUE=DATE-TIME:20231109T091500Z DTSTAMP;VALUE=DATE-TIME:20260305T082036Z UID:indico-contribution-300-1297@events.ncbj.gov.pl DESCRIPTION:Speakers: Michał Jędrzejczyk (National Centre for Nuclear Re search)\nThe multiplication factor (keff) and its uncertainty are critical design parameters in nuclear reactors. Reducing this uncertainty would he lp in achieving more optimal design and safer operation of nuclear reactor s. This uncertainty mostly comes from neutron cross-section uncertainties. It is difficult to measure the neutron cross-sections more accurately wit h direct measurements using currently available technologies. In this semi nar three Bayesian algorithms allowing for more accurate indirect measurem ents are presented. The potential to ultimately reduce the keff uncertaint y by applying such algorithms is presented on an example.\nA list of best practices for conducting uncertainty reduction with Bayesian methods is es tablished. The compilation of such list was motivated by absence of these practices in many papers which apply Bayesian methods for uncertainty redu ction or quantification in the field of nuclear engineering. These best pr actices include a rigorous procedure for validation of posterior results b ased on so-called “synthetic experiments” and improved prior uncertain ty quantification of experimental data assimilated with Bayesian algorithm s.\n\nhttps://events.ncbj.gov.pl/event/300/contributions/1297/ LOCATION:NCBJ Room 207 URL:https://events.ncbj.gov.pl/event/300/contributions/1297/ END:VEVENT BEGIN:VEVENT SUMMARY:Warsaw macro-micro model and random walk method for calculating th e fusion probability of superheavy elements DTSTART;VALUE=DATE-TIME:20231026T071500Z DTEND;VALUE=DATE-TIME:20231026T081500Z DTSTAMP;VALUE=DATE-TIME:20260305T082036Z UID:indico-contribution-300-1299@events.ncbj.gov.pl DESCRIPTION:Speakers: Aleksander Augustyn (NCBJ)\nOne of the important\, o ngoing goals in nuclear physics is the creation of superheavy elements wit h Z=119 and Z-120. The experiments which try to achieve this objective are very time-consuming\, because of the low production cross sections. Theor etical calculations may give valuable insight into choosing the most effec tive reactions and bombarding energies for experimentalists.\nIn this talk \, a new method for predicting the probability of fusion of superheavy ele ments will be presented. The approach uses a random walk algorithm\, in wh ich the shape evolution is governed by the density of states above the mul tidimensional potential energy surface (PES). The PESs were calculated wit hin the latest version of the Warsaw macroscopic-microscopic model [1]\, w ith rotational energy included. \nThree cold fusion reactions will be exam ined in detail: 48Ca+208Pb\, 50Ti+208Pb and 54Cr+208Pb. The calculated pro babilities of fusion for these reactions will be shown. The influence of a ngular momentum and excitation energy on ratios of symmetric and asymmetri c divisions will be demonstrated. Future improvements to the method will a lso be discussed.\n\n[1] P.

A small Dirac mass for the neutrinos appe ars more naturally in the B-L model compared to the standard model\, when we account for quantum gravity corrections based on existing calculations . This mechanism can also accommodate Majorana neutrinos and pseudo-Dirac neutrinos\, for various values of seesaw scale. I will discuss whether gra vitational waves from first-order phase transition can distinguish these c ases. In the presence of quantum scale invariance of the scalar potential -- which is at odds with existing calculations in asymptotically safe quan tum gravity -- we find no gravitational wave signals. Forgoing this symmet ry\, we find an observable signal in new-generation space interferometers. However\, its discriminating features are washed out due to the stro ng dependence of the gravitational-wave spectrum on the mass parameter of the scalar potential.\n\nhttps://events.ncbj.gov.pl/event/300/contribution s/1301/ LOCATION:NCBJ Room 207 URL:https://events.ncbj.gov.pl/event/300/contributions/1301/ END:VEVENT BEGIN:VEVENT SUMMARY:Welcoming talk of the Graduate School director DTSTART;VALUE=DATE-TIME:20231005T071500Z DTEND;VALUE=DATE-TIME:20231005T073500Z DTSTAMP;VALUE=DATE-TIME:20260305T082036Z UID:indico-contribution-300-1303@events.ncbj.gov.pl DESCRIPTION:Speakers: Michał Spalliński (NCBJ)\nhttps://events.ncbj.gov. pl/event/300/contributions/1303/ LOCATION:NCBJ Room 207 URL:https://events.ncbj.gov.pl/event/300/contributions/1303/ END:VEVENT BEGIN:VEVENT SUMMARY:Discussion about the goals and organization of the PhD seminar DTSTART;VALUE=DATE-TIME:20231005T073500Z DTEND;VALUE=DATE-TIME:20231005T075500Z DTSTAMP;VALUE=DATE-TIME:20260305T082036Z UID:indico-contribution-300-1302@events.ncbj.gov.pl DESCRIPTION:Speakers: Jakub Wagner (National Centre for Nuclear Research)\ , Katarzyna Malek (NCBJ)\, Michal Bluj (NCBJ)\nhttps://events.ncbj.gov.pl/ event/300/contributions/1302/ LOCATION:NCBJ Room 207 URL:https://events.ncbj.gov.pl/event/300/contributions/1302/ END:VEVENT BEGIN:VEVENT SUMMARY:Deeply virtual scattering in QCD DTSTART;VALUE=DATE-TIME:20231019T071500Z DTEND;VALUE=DATE-TIME:20231019T081500Z DTSTAMP;VALUE=DATE-TIME:20260305T082036Z UID:indico-contribution-300-1300@events.ncbj.gov.pl DESCRIPTION:Speakers: Victor Martinez-Fernandez ()\nFor a long time\, it w as believed that the fundamental constituents of atoms were electrons and nucleons being both elementary. Experiments conducted in the late 1960s at Standford Linear Accelerator Center (SLAC) proved the existence of intern al degrees of freedom in the nucleons. These ones are called quarks and gl uons\, or collectively partons. With QCD as the fundamental theory for str ong interactions\, we can describe hadronic structure via correlators of p artons giving rise to the so-called parton distribution functions (PDFs) a nd generalized parton distributions (GPDs) when the so-called collinear fa ctorization applies. The non-elementary nature of hadrons makes these corr elators perturbatively unsolvable so we can only measure or model them.\n\ nThis seminar attempts to show the different ways to access such correlato rs and how they provide information on the structure of the hadrons. For t his purpose\, different processes in QCD will be explained and the latest results in theory and phenomenology will be discussed.\n\nhttps://events.n cbj.gov.pl/event/300/contributions/1300/ LOCATION:NCBJ Room 207 URL:https://events.ncbj.gov.pl/event/300/contributions/1300/ END:VEVENT BEGIN:VEVENT SUMMARY:Measurements of 10 ps lifetime of 10+ state in 128Cs – experimen t and analysis.
