Room: Room 207
In our recent work [1], we introduced a novel approach, the Dipole-Driven Model (DDM), for characterizing the fusion process of two heavy ions within the entrance channel. The DDM utilizes the dipole variable as an authentic shape parameter to describe the configuration of the colliding heavy ions, with shape parametrization performed at the neck region. This allows for the optimization of the deformation space and the exploration of previously unattainable shapes. In this talk, a new method for predicting the probability of fusion of superheavy elements will be presented. The approach uses a random walk algorithm, in which the shape evolution is governed by the density of states above the multidimensional potential energy surface (PES). The PESs were calculated within the latest version of the Warsaw macroscopic-microscopic model [1], with rotational energy included. Three cold fusion reactions will be examined in detail: 48Ca+208Pb, 50Ti+208Pb and 54Cr+208Pb. The calculated probabilities of fusion for these reactions will be shown. The influence of angular momentum and excitation energy on ratios of symmetric and asymmetric divisions will be demonstrated. Future improvements to the method will also be discussed. [1] T. Cap, A.

09:15 - 10:00
Room: Room 207
In this seminar, I will present a study of Vector Boson Scattering (VBS) processes at the Compact Muon Solenoid (CMS) experiment at CERN, with a specific focus on the scattering of same-sign W bosons. The final state under investigation involves two leptons, two neutrinos and two tagging jets. My analysis will explore key VBS processes, detailing the challenges posed by various backgrounds and the strategies employed to mitigate their contributions. In particular, I will highlight the impact of non-prompt leptons, which represent one of the most significant backgrounds, and explain how these are addressed in our study. Additionally, I will share insights from the data analysis, including results related to the interpretation within the framework of the Standard Model Effective Field Theory (SMEFT).

Room: Room 207
Unveiling the routes galaxies take to quiescence is one of the most open challenges in galaxy evolution. While the most of studies focused on characterizing quiescent galaxies (QG) across cosmic time through their stellar properties using optical/near-infrared (NIR) data, the mid-infrared regime was only recently examined thanks to the advent of JWST. The need to understand the MIR emission in QGs has been emphasized due to recent discoveries of a peculiar population of quiescent, but dust-rich galaxies at high-redshitts (z>0.5-3). In this talk, I will present the preliminary results of a first study that investigated the quenching routes and the physical properties of MIRI-bright, dust-attenuated QGs in the distant universe.

Room: Room 207
The direct detection of gravitational waves (GWs) by the LIGO Science Collaboration marked the beginning of a new era in astronomy, allowing us to probe previously inaccessible realms of the universe. Among the most exciting prospects in this field is the detection of gravitationally lensed GWs, which could reveal valuable insights about intervening mass distributions in space. While much attention has focused on detecting lensing in GWs from merging compact binaries, little exploration has been directed toward the lensing of GWs emitted by isolated neutron stars. These GWs are continuous and monochromatic, differing significantly from the transient "chirp" signals we typically observe. In this talk, I will discuss our findings on the lensing of continuous GWs by dark mini-halos and demonstrate how the relative motion between the lens, source, and observer can produce a distinctive microlensing pattern. This work opens new avenues in the study of GW lensing and could provide unique insights into the nature of dark matter besides enhancing the detectability of a signal.

Room: Room 207
In the upcoming muon collider, high-energy collisions between muons and antimuons will reach center-of-mass energies up to 10 TeV. Decays of these muons in the beam pipe will produce a high-energy muon neutrino beam. The energy and intensity of the beam, as well as its well-known energy spectrum, provide a unique opportunity to study neutrino properties and interactions, potentially uncovering new physics beyond the Standard Model. In this talk, I will discuss the prospects for detecting new mediators that couple predominantly to neutrinos with masses in the 1 MeV to 100 GeV range with low coupling strengths. Such a neutrinophillic mediator, which could couple to the dark sector, is a well-motivated candidate for opening new avenues in the search for neutrino portal dark matter. The corresponding signature would include neutrino charged-current scattering events associated with positively charged muons.

Nuclear chirality, a phenomenon known for only 27 years, is being found in more and more different nuclei, around 60 isotopes found to date. Nuclear chirality can occur in the excited state when the nuclei is triaxially deformed. In this seminar, I will show why and how we examine excited states in nuclei, what is the nuclear chirality, and how it can be found. I will also show the final results of the experiment performed in July 2022 at Heavy Ion Laboratory in Warsaw and state the most important outcomes.
