DESCRIPTION:Speakers: Shuaibo Geng (National Center for Nuclear Research)\
 nGravitational lensing\, as predicted by Einstein's General Relativity\, i
 s the bending of light from distant sources via the gravitational field of
  massive objects. This phenomenon provides a valuable opportunity for uniq
 ue studies. In this presentation\, I will discuss the applications of stro
 ng gravitational lensing in the realms of cosmology and galaxy evolution.\
 n\nUsing the most extensive current sample of early-type galaxies (ETGs) l
 ensing systems\, we probe the velocity dispersion function (VDF) and trace
  its evolution at redshift z ∼ 1. Our findings align with the SDSS surve
 y results\, revealing a halving of number density and a 20% increase in ch
 aracteristic velocity dispersion for ETGs at z ∼ 1\, supporting the Cold
  Dark Matter (CDM) paradigm. We've used model-independent methods to recon
 struct distance ratios and time-delay distances by lensing systems\, which
  help us limit the parameters of various cosmological models. The derived 
 Hubble constant (H0) is in agreement with the SH0ES collaboration findings
  from the cosmic distance ladder. And the zero spatial curvature is suppor
 ted by the current observations of time delays due to strong lensing and c
 osmic chronometers. The forthcoming LSST survey\, with its expected larger
  sample\, could enhance the precision of redshift evolution constraints of
  ETGs by a factor of twenty. Furthermore\, it can estimate the matter dens
 ity parameter Ωm with an accuracy of ΔΩ~0.015 in the ΛCDM model\, offe
 ring constraints comparable to Planck 2015's results.\n\nhttps://events.nc

DESCRIPTION:Speakers: Salil Joshi (NCBJ)\nOut of all the unexpected elemen
 tary particles discovered in the past two decades\, the 30 or so observed 
 exotic hadrons candidate i.e.\, ones that do not fit into the paradigms of
  either bosonic or fermionic baryons. A new era in the study of QCD exotic
 a began in 2003 with the accidental discovery of the X(3872) by the Belle 
 Collaboration\, noticed a narrow peak in the invariant mass spectrum of th
 e pi+pi-J/psi system. Most of these states discovered have masses in the s
 ame region as conventional charmonium states (charmonium-like) or bottomon
 ium-like. Although being the most unambiguous candidates for exotic hadron
 s observed to date\, no scientific consensus has yet emerged to explain al
 l of them and their formation\, properties\, structure by means of a singl
 e\, universal theoretical principle. The LHCb announced in 2022 the discov
 ery of a new penta-quark particle and a doubly electrically charged tetra-
 quark with its neutral counterpart\, with a staggering statistical signifi
 cance of 7.3 sigma and 6.5 sigma\, respectively. It is this pattern of one
  unexpected result after another\, with the emergence of desperately few c
 onnections\, that has characterized the last 20 years of experimental stud
 ies in this field. This presentation is aimed at introducing this rapidly 
 expanding field of QCD exotica\, theoretical aspects and experimental tech
 niques used for studying these incredible anomalies.\n\nhttps://events.ncb

DESCRIPTION:Speakers: Michał Mazurek (NCBJ)\nCurrent and future experimen

  to the interpretation of physics measurements\, as well as the design and
  performance of new detectors. In order to be able to produce all the nece
 ssary simulated samples\, new simulation techniques and software technolog
 ies are needed\, also requiring careful evaluation already at prototype le
 vel. In this talk\, I will present Gaussino - a new simulation experiment-
 independent framework that provides generic core components to build a com
 plete simulation application: generation\, detector simulation\, geometry\
 , monitoring\, saving persistent simulated data\, as well as interfaces to
  various fast simulations and machine learning libraries. I will also show
  how Gaussino can be used to explore new detector ideas\, and then seamles
 sly integrated in experiment's production-ready simulation setup developed
  within the scope of the same simulation framework.\n\nhttps://events.ncbj

DESCRIPTION:Speakers: Sushobhan Mandal (NCBJ)\nDirect photons serve as uni
 que probes in high-energy proton-proton and nucleus-nucleus collisions\, i
 nteracting weakly with the dense and hot quark-gluon medium formed during 
 these events. These photons escape freely\, providing undistorted informat
 ion about the collision's evolution. The Quark-Gluon Plasma (QGP)\, compri
 sing deconfined quarks and gluons\, is believed to have existed in the Uni
 verse shortly after the Big Bang. As the QGP cools\, it transitions into t
 he hadronic matter that we observe today. In laboratory settings\, small-s
 cale "Big Bangs" are artificially created through high-energy heavy-ion co
 llisions\, which heat the hadronic matter to temperatures of approximately
  150 MeV\, leading to the formation of the QGP. By studying prompt\, pre-e
 quilibrium\, and thermal photons emitted during these collisions\, we can 
 estimate the effects of cold and hot nuclear matter and gain insights into
  the temperature\, correlations\, and collective phenomena within the QGP.

DESCRIPTION:Speakers: Mahmoud Hamed (NCBJ)\nDespite its low contribution t
 o the total mass of the interstellar medium\, dust plays a crucial role in
  the evolution of galaxies\, and it has the biggest impact on the shape of
  their total spectral energy distribution. Dust attenuates the stellar lig
 ht by absorbing the short wavelength photons incoming from the newly-forme
 d stars\, and emits them thermally in the infrared.  To account for dust a
 ttenuation in models\, one should assume a dust attenuation law which desc
 ribes how stellar emission is absorbed by dust.  Despite the growing knowl
 edge in the field of extragalactic astronomy\, key questions remain unansw
 ered: What dust attenuation law one should use at high redshift? What are 
 the physical conditions on which dust attenuation curves depend?\nIn this 
 talk\, I will present the key physical processes that affect the curve of 
 dust attenuation\, in a large study of dusty star-forming galaxies from th
 e early Universe until the present times.\n\nhttps://events.ncbj.gov.pl/ev

DESCRIPTION:Speakers: Hareesh Thuruthipilly (National Center for Nuclear R
 esearch (NCBJ))\nLow surface brightness galaxies (LSBGs) are defined as ga
 laxies that are fainter than the night sky (µ(g) > 22 mag arcsec−2). LS
 BGs are hypothesized to be dominated by dark matter halos and contain a si
 gnificant fraction of the missing baryons\, making them an ideal laborator
 y to test cosmological models. Upcoming large-scale surveys like Rubin Obs
 ervatory Legacy Survey of Space and Time (LSST) and Euclid are expected to
  observe approximately 10^9\n astronomical objects. In this context\, usin
 g semi-automatic methods to identify LSBGs while rejecting artefacts would
  be highly challenging and time-consuming. Therefore\, alternative approac
 hes such as automated or machine learning-based methods will be necessary 
 to overcome this challenge. We study the use of transformers or\, more gen
 erally\, the self-attention-based machine learning models in separating LS
 BGs from artefacts from the Dark Energy Survey (DES). In addition\, we als
 o searched for the presence of new LSBGs from DES that the previous search
 es may have missed. Using an ensemble model\, we identified 4083 LSBGs fro
 m the DES data release 1 (DR1)\, adding an additional ~17% LSBGS to the kn
 ow LSBGs. We analyze the properties of these new LSBGs and the general pro
 perties of LSBGS in DES.\n\nhttps://events.ncbj.gov.pl/event/222/contribut

DESCRIPTION:Speakers: Arantxa Tymowska (NCBJ)\nOne very promising observab

 on at forward rapidity in proton-nucleus collisions. Since the produced ph
 oton does not rescatter on the target\, this observable provides a clean e
 nvironment to study the interaction of the quark probe with the dense targ
 et.\nIn this talk\, we will present the results for the photon-quark produ
 ction cross-section (as a proxy for photon+jet) at next-to-eikonal accurac
 y taking into account finite-width target effects\, dynamics of the target
  and the interaction with the subleading components of the background fiel
 d. Moreover\, we will also discuss the link between the high-energy Color 
 Glass Condensate (CGC) formalism and the TMD factorization for this specif

 os comprises of muon and electron neutrinos. Below 10 GeV\, we do not expe
 ct to see a significant number of tau neutrinos in the atmosphere\, unless
  they appear from the oscillation of atmospheric muon neutrinos. The Super
 -Kamiokande experiment (Super-K) is a water Cherenkov detector in Japan. S
 uper-K is capable of directly detecting these oscillated tau neutrinos - w
 hich would be an unambiguous confirmation of the phenomena of neutrino osc
 illations. The last study at Super-K\, in 2018\, excluded the hypothesis o
 f no tau neutrino appearance at 4.6 sigma. This seminar presents the lates

 hen introduce its semi-classical approximation. We employ a general integr
 al quantization method that respects the symmetries of the model given by 
 the affine and the Weyl-Heisenberg groups\, and can produce a wide class o
 f quantum models. The semi-classical approximation is based on the coheren
 t states. The semi-classical dynamics is complex and can not be solved by 
 analytical methods. We focus on a key qualitative feature of the dynamics\
 , namely\, we investigate whether the primordial anisotropic universe can 
 undergo a spontaneous inflationary phase driven by the anisotropic energy 
 combined with semi-classical corrections. The answer to this question prov
 ides a useful perspective on the inflationary paradigm as well as on alter
 native bouncing models.\n\nhttps://events.ncbj.gov.pl/event/222/contributi

DESCRIPTION:Speakers: Alice Boldrin (NCBJ)\nThe problem of time in physics
  arises from the conceptual discrepancies between non-relativistic and rel
 ativistic time.\nThe principle of general covariance in general relativity
  gives us the freedom to choose an arbitrary clock for our theory. In quan
 tum mechanics\, however\, different choices of internal time variables are
  known to produce unitarily inequivalent quantum models.\nIn my presentati
 on I will propose a fully analytical model of primordial gravitational wav
 es propagating in a Friedman-Lemaitre-Robinson-Walker background with diff
 erent clocks to study what are (if any) the dynamical predictions of quant
 um gravity models for large classical universes\, which do not depend on t
 he employed time variable.\nSolving the Hamiltonian constraint of the mode
 l and fixing the internal time variable prior to quantization\, we are abl
 e to study all the existing clocks and quantize them in a way that ensures
  a fixed ‘operator ordering’.\nHence\, any quantum ambiguity found is 
 safely ascribed to the different choice of clock.\n\nhttps://events.ncbj.g

DESCRIPTION:Speakers: Michał Jędrzejczyk (National Centre for Nuclear Re
 search)\nIn the past\, modeling of some of the nuclear reactors' operation
 al parameters was done using conservative input values in cases where the 
 uncertainty of inputs was not available or easily quantifiable. This appro
 ach led to deteriorated economical performance of the reactors\, as conser
 vative modeling outputs strayed far from actual operational conditions. Mo
 dern computing resources combined with Inverse Uncertainty Quantification 
 (IUQ) methods allow quantifying uncertainties in input parameters for whic
 h previously only point estimates were known. IUQ is conducted by assimila
 ting data from appropriate experiments or previously operated nuclear reac
 tors. Quantifying inputs' uncertainty allows for switching from a conserva
 tive modeling style to the Best Estimate Plus Uncertainty (BEPU) standard 
 in which we estimate the most likely value of the experimental result plus
  its uncertainty. BEPU methodology adheres to nuclear reactor licensing re
 quirements while making the reactors' design more economical.\nIn this sem
 inar\, I introduce IUQ in the context of nuclear reactor engineering\, foc
 using on the Bayesian IUQ methods.\n\nhttps://events.ncbj.gov.pl/event/222

DESCRIPTION:Speakers: Andrea Bevilacqua (NCBJ Warsaw)\nIt is commonly expe
 cted that the usual description of spacetime as a smooth manifold is no lo
 nger reliable as we approach the Planck scale when quantum effects of the 
 geometry can no longer be neglected. Noncommutativity of spacetime has bee
 n advocated as a possible way to effectively model quantum gravitational e
 ffects in regimes of negligible curvature. A widely studied incarnation of
  this idea suggests that the scale of noncommutativity should be seen as a
 n  observer-independent length scale and that\, in order to accommodate su
 ch a fundamental scale\, ordinary relativistic symmetries should be deform
 ed (keeping in mind that they should reproduce the usual Poincaré algebra
  in the limit of vanishing noncommutativity). The κ-Poincaré algebra is 
 an example of such deformation.\n\nIn this talk I will briefly describe a 
 construction of a κ-deformed complex scalar field theory\, while at the s
 ame time shedding light on the behaviour of discrete and continuous symmet
 ries in this formalism. This in turn will open the way to the study of the
  application of this formalism to actual physical processes. I will then c

DESCRIPTION:Speakers: Gabriele Riccio (National Centre of Nuclear Research
 \, Warsaw)\nStar formation is one of the main mechanisms of energy product
 ion in the universe and one of the essential processes linked to galaxies'
  evolution. Over the past two decades\, we have witnessed an explosion of 
 data from local and distant galaxies across the entire electromagnetic spe
 ctrum. These observations gave us an unprecedented picture of those object
 s (e.g. gas content\, physical conditions in the interstellar medium\, and
  dynamical state of galaxies) and their evolution over cosmic time. But th
 e main problem of proper and homogeneous estimation of the star formation 
 rate (SFR) is still open.\nThe common denominator in all these studies is 
 the use of diverse techniques for quantifying the recent star-forming acti
 vity in different environments. This talk aims to introduce the methods us
 ed to measure the intensity of star-forming activity in galaxies (their st
 ar-formation rates)\, focusing on spectral energy distribution (SED) fitti
 ng methods and star formation rate evaluation from the galaxy X-ray emissi
 on. In this context\, I will discuss my PhD project\, dividing it into thr
 ee parts: 1) Is it possible to estimate proper SFR for normal star-forming
  galaxies for the upcoming optical Legacy Survey of Space and Time (LSST) 
 data from the Vera C. Rubin Observatory? 2) How does the emission from low
 -mass X-ray binaries contribute to galaxies' total X-ray emission\, and ho
 w does it influence the SFR measurement? 3) How the X-ray emission modelin
 g can help us probe the X-ray luminosity-SFR scaling relation\n\nhttps://e

DESCRIPTION:Speakers: Sreekanth Harikumar (National Centre for Nuclear Res
 earch(NCBJ))\nGravitational lensing has been considered as a rare phenomen
 on\, however recent advancements in technology lead to the discovery of ma
 ny lensed events. Now it has become an unavoidable tool in astronomy. Like
  electromagnetic waves\, gravitational waves could also be lensed leading 
 to the formation of magnified multiple signals and many more. The increasi
 ng sensitivity of current detectors and planned next-generation detectors 
 makes the future of gravitational wave astronomy looks promising. In this 
 talk\, I will present some of the interesting predictions of lensed gravit
 ational waves and how such lensed events can be used to test modified theo
 ries of gravity.\n\nhttps://events.ncbj.gov.pl/event/222/contributions/107

DESCRIPTION:Speakers: Mateusz Kmieć (NCBJ)\nThe Standard Model of particl
 e physics (SM) is the embodiment of our current understanding of the sub-a
 tomic Universe and describes all fundamental forces except gravity. Despit
 e its success\, the SM has a few shortcomings. Apart from not including th
 e description of gravity\, it fails to explain the scale of the observed m
 atter-antimatter imbalance and does not give the rationale behind the appa
 rent non-zero neutrino masses. These problems are at the core of particle 
 physics research today\, as even a minor deviation from the SM (such as CP
 T violation) would be a breakthrough suggesting the existence of a more fu
 ndamental theory beyond the SM (BSM). The BSM effects are expected to be v
 ery small\, for example at the Planck scale.\n\nFortunately\, physics at t
 he scale approaching the Planc scale can be tested with existing technolog
 y through the search for spacetime-symmetry violation. The realisation of 
 this fact brought about the development of a comprehensive framework\, kno
 wn as the Standard Model Extension (SME). It was set up for studying devia
 tions from exact Lorentz and CPT symmetries. This framework can be success
 fully applied to studies of CPT violation (CPTV) in neutral meson oscillat
 ions. Where the order of magnitude of results of CPTV measurements with ne
 utral kaons approaches an interesting region of m^2_{K}/M_Planck=2*10^{-20
 } GeV. In my talk\, I will try to outline the basic notions regarding the 
 theoretical description of neutral meson oscillations\, as well as\, the k
 ey concepts behind the analysis regarding the search for CPT breaking in t
 he charm sector.\n\nhttps://events.ncbj.gov.pl/event/222/contributions/106

DESCRIPTION:Speakers: Swaleha Mulani (National Centre for Nuclear Research
 (NCBJ)\, Warsaw\, Poland)\nStudying high-energy hadronic scattering proces
 ses to understand the interior of atoms has been the focus of experimental
  and theoretical studies for more than three decades now. During this peri
 od\, the Color Glass Condensate(CGC) effective field theory has been utili
 sed to analyse specifically high-energy proton-nucleus (pA) collisions. On
 e of the main approximations used in the CGC is the so-called eikonal appr
 oximation\, which amounts to neglecting power-suppressed corrections in hi
 gh-energy limits. For high-energy colliders like LHC\, this is a good enou
 gh approximation. But the corrections beyond eikonal approximation can be 
 sizable at intermediate energies\, in particular at relativistic heavy ion
  collider (RHIC) and upcoming electron ion collider (EIC). In this talk\, 
 I will briefly review the eikonal approximation and present the computatio
 n of a gluon propagator through the target at next-to-eikonal accuracy.\n\

DESCRIPTION:Speakers: Luis Eduardo Suelves (NCBJ)\nIn my talk\, I will pre
 sent work on identifying mergers of galaxies using astronomical data in op
 tical bands. The current models of galaxy formation and evolution\, in the
  context of the Lambda-CDM cosmological model\, are based on dark matter h
 aloes that host a galaxy. Merging galaxies are one crucial aspect of the g
 alactic life-time whose effect is still not fully understood. Identifying 
 them is therefore the research first step. Two projects will be presented:
  first the use of image recognition methods with a Convolutional Neural Ne
 twork (CNN) together with morphological parameters on the North Ecliptic P
 ole (Pearson\, Suelves et al. 2022). This provided the community with a ca
 talogue of mergers in one region of the sky with a wealth of data across t
 he electromagnetic spectrum. The second is the application of a Neural Net
 work (NN) applied on photometric information (Suelves\, Pearson \\& Pollo 
 2022). This NN provided us with a previously unknown tracer of merging pro
 cesses\, the error in the sky background calculation. With it\, we aim to 
 make merger finding techniques more efficient and less prone to mistakes d
 ue to the complexity of the night sky.\n\nhttps://events.ncbj.gov.pl/event

DESCRIPTION:Speakers: Victor Martinez-Fernandez ()\nFor a long time\, it w
 as believed that the fundamental constituents of atoms were electrons and 
 nucleons until experiments conducted in the 1960s at Standford Linear Acce
 lerator Center (SLAC) proved the existence of internal degrees of freedom 
 in the nucleons. These ones are called quarks and gluons\, or collectively
  partons. With QCD as the fundamental theory for strong interactions\, we 
 can describe hadronic structure via correlators of partons giving rise to 
 the so-called parton distribution functions (PDFs) and generalized parton 
 distributions (GPDs). The non-elementary nature of hadrons makes these cor
 relators perturbatively unsolvable so we can only measure or model them. O
 n top of this\, PDFs and GPDs appear when studying two different types of 
 QCD processes: inclusive and exclusive. Among all known processes of these
  two types\, there is an exclusive scattering named double deeply virtual 
 Compton scattering (DDVCS) that allows to measure GPDs in their whole doma
 in. \n\nIn this seminar\, I review the differences between inclusive and e
 xclusive processes with special attention to DDVCS for which my group and 
 I have obtained a new analytical formulae useful to study its feasibility 
 in JLab and EIC experiments.\n\nhttps://events.ncbj.gov.pl/event/222/contr

DESCRIPTION:Speakers: Nora Salone ()\nThough weak non-leptonic decays of h
 yperons - strange baryons - have been investigated before\, an update is u
 rgently needed in view of recent significant measurements from the BESIII 
 collaboration. Only with such an update\, future high-precision data of we
 ak non-leptonic decays can be properly interpreted. Such hadronic decays a
 re characterized by two distinct contributions to the decay amplitude\, ca
 lled S- and P-wave.\nWithin the framework of chiral perturbation theory (
 χPT)\, such L-wave amplitudes can be computed: we do so up to one-loop co
 rrections\, noting also that in recent years their relative size to the tr
 ee-level contributions was differently interpreted. The general consensus 
 is that weak non-leptonic hyperon decays are characterized by two contribu
 tions with polar behavior under approximate SU(3) symmetry.\nThis project 
 aims at reviewing such calculations in the light of the recent updates on 
 the measurement of the decay parameter αΛ\, directly connected to the ab
 ove-mentioned spherical-wave amplitudes. A recalculation of such lowest or
 der contributions and their corrections is hence needed\, since it might l
 ead to a new level of agreement with experiment. As an additional bonus\, 
 our aspiration is to reduce the numerous different approaches to the best 
 fitting description of such decays.\n\nhttps://events.ncbj.gov.pl/event/22

DESCRIPTION:Speakers: Margherita Grespan (NCBJ)\nThe development of new al
 l-sky and large-area astronomical surveys gives a chance for new insights 
 in astrophysics. However\, these recent generation surveys are flooding as
 tronomers with data\, giving an exponential growth - with respect to previ
 ous surveys - of data collected per night (for instance\, 90 TB/night for 
 the Thirty Meter Telescope). For some tasks\, i.e. object detection\, clas
 sical methods or human detection need to be faster to cover the totality o
 f the data collected. At the same time\, Machine learning (ML) keeps showi
 ng the scientific community its ability to solve astrophysical problems.\n
 In this talk\, I will show some ML applications on astrophysical data in d
 ifferent domains: time and frequency domain gravitational waves (GW) data\
 , strong lenses detection (images)\, and astronomical text interpretation.
  The emphasis will be put on analysis related to Strong gravitational lens
 ing and on the importance of having explainable Artificial Intelligence. S
 trong gravitational lensing is useful to constrain cosmological parameters
 \, even though it is a rare phenomenon in astrophysics. For this reason\, 
 strong lens seekers are training their ML models on simulations. We will s
 how how simulation-trained models behave with survey data\, interpret the 
 results and discuss techniques that might help us research new candidates.
  Finally\, I will discuss possible applications of Interactive ML for obje
 ct detection.\n\nhttps://events.ncbj.gov.pl/event/222/contributions/1041/

DESCRIPTION:Speakers: Daniele Rizzo (National Center for Nuclear Research 
 (NCBJ)\, Warsaw\, Poland)\nThe pursuit for physics beyond the Standard Mod
 el (BSM) follows a twofold path. On the experimental side\, a great effort
  was put in developing research strategies that go beyond the original LHC
  paradigm based on the missing transverse energy. On the theoretical side\
 , various BSM models can be proposed to address phenomena observed in natu
 re. Among many extensions of the Standard Model\, scenarios with vector-li
 ke (VL) fermions and Z' have long been enjoying a lot of interest. In this
  presentation I will talk about two different models with VL-fermions and 
 Z'. In the first model I use the framework of Trans-Planckian Asymptotic-S
 afety to reduce the number of free parameters of a minimal model with VL-f
 ermions and Z'. In the second model I scan the parameter space of a slight
 ly modified version of the type-II next-to-2HDM. One of the main features 
 of this second model is that masses for SM particles are generated via the
  so-called Seesaw mechanism.\n\nhttps://events.ncbj.gov.pl/event/222/contr

DESCRIPTION:Speakers: Abhishek Chikkaballi ()\nThe Standard Model is a ver
 y successful theory. However\, few of the observed phenomenon is at odds w
 ith the current fundamental theory. One such discrepancy is observed in th
 e rare decays of B-meson decays which are referred as flavor anomalies. In
  this talk\, I will discuss flavor-anomaly solutions with U(1)` extensions
  in the framework of asymptotically safe quantum gravity. The universal co
 ntribution of quantum gravity to renormalization group equations (RGEs) of
  all the gauge and the Yukawa couplings\, beyond the Planck scale\, ensues
  interdependent boundary conditions between the Standard Model and the New
  Physics (NP) couplings during the flow of RGEs from an interactive UV fix
 ed point. As a result\, precise measurements of low-energy SM couplings fi
 x the exact values of the NP couplings\, and accordingly\, the NP mass ran
 ge can be significantly narrowed down. We confront the models parameter sp
 ace with the various LHC searches for VL fermions and the new gauge boson 
 Z'. We find a viable parameter space with a potential to probe entirely in
  LHC Run 3.\n\nhttps://events.ncbj.gov.pl/event/222/contributions/1037/
