The Neutron Skin (NS), which is a phenomenon of an increased neutron to proton density ratio in the periphery of neutron-rich nuclei, is a prominent probe of the nuclear equation of state, connecting nuclear physics and astrophysics. However, the theoretical predictions and experimental measurements of the NS in $^{208}$Pb have been contradictory. The PREX-II experiment resulted in a much...

The ALICE Inner Tracking System (ITS2) will be upgraded for LHC Run 4. The upgrade project foresees the replacement of the three innermost layers of the ITS2 with a truly cylindrical vertex detector, the ITS3. This innovative tracker will be composed of three self-supporting layers, each comprising two large-area (O(10×26 cm2)), ultra-thin (20 – 40 µm) and flexible stitched Monolithic Active...

ATOMKI Collaboration (Debrecen) observed anomalies in the angular distribution of e+e− pairs emitted via Internal pair Conversion (IPC) during nuclear de-excitation of the 8Be, 4He, and 12C. This enhancements seem to be compatible with the production, and successive decay, of a new vector boson with a mass of ∼ 17 MeV. PADME Collaboration performed an invariant mass scan in the sensible region...

In students' conference I want to introduce the discussion on the HEP's yet unsolved problem of possible CPT violation and baryon asymmetry of the universe (BAU), on which I was trying to work with Associate Prof. Merab Gogberashvili for my Bachelor's degree. After Anderson's discovery of the positron, the problem was obvious: for some unknown reasons the observable universe is matter...

The method of moments has been employed to derive relativistic fluid-dynamical theories from the Boltzmann equation for the past decades [1]. This approach consists in expanding the single-particle distribution function using a basis of irreducible momenta, where the expansion coefficients are the irreducible moments of the nonequilibrium distribution function [2]. Unlike the Chapman-Enskog...

The nucleon–nucleon interaction may lead to the creation of clusters, mainly α-particles, inside the nuclear medium. The investigation of nuclear clustering has been a long-standing area of study and different experiments have been conducted with a variety of α-conjugated nuclei, mainly at the Coulomb barrier and Fermi energy range (1-100 MeV). The FOOT experiment aims to investigate the...

The ALICE experiment at CERN is in the process of upgrading its Inner Tracking System (ITS). This upgrade (ITS3), involves replacing the innermost tracking layers with wafer scale cylindrically bent MAPS (Monolithic Active Pixel Sensors) chips. The inner layers will be positioned closer to the collision points while significantly reducing the material budget, which will notably enhance the...

A compilation of the experimental p+p data of neutral and charged kaon production has revealed a discrepancy between the observed K0 s yield and the the average number of produced charged kaons K0 s = (K+ +K−)/2. This widespread relation holds only for a colliding system that is an uniform population w.r. to the isospin (i.e. that consists of an equal number of all members of a given isospin...

R&D efforts are ongoing to develop a cylindrical Micromegas tracker for the central barrel of the ePIC detector, the first experiment at the future Electron Ion Collider (EIC). The Micromegas detectors will be a part of a multi-technology tracker that needs to fit inside a 1.7 T solenoid, bringing stringent constraints on space, material budget and number of electronic channels. As such, a...

The Belle-II experiment with its e+e− collisions allow observations of exotic states, complementa- ry to those in heavy-ion collisions as for example at LHCb. The Belle-II detector is commissioned at the SuperKEKB B-Factory in Japan and provides vital conditions for the study of such states. A bound state with six quarks and uuddss-content has strangeness quantum-number (−2) and would be the...

Using data collected in pp collisions at √s = 13 TeV with the ALICE detector during the Run 2 period of the LHC, the femtoscopy technique has been successfully employed to extend the boundaries of known hadron-hadron interactions into the S = -3 sector and to initiate studies of charmed and three-body systems. The key element of these analyzes is the assumption of a common particle emitting...

Elastically scattered electrons polarised perpendicular to the scattering plane will exhibit a count rate asymmetry (A$_{n}$) amongst left and right, which can be used as a probe for multi photon exchange contributions to the scattering amplitude. While for most target nuclei A$_{n}$ is in good agreement with the theoretical predictions, previuos measurements on $^{208}$Pb obtained values...

Linear stability of Israel-Stewart theory in the presence of net-charge diffusion was investigated in [C. V. Brito and G. S. Denicol, Linear stability of Israel-Stewart theory in the presence of net-charge diffusion, Phys. Rev. D 102, 116009 (2020)] for the case of a massless, classical gas of noninteracting particles. However, in that work only a vanishing net-charge background was...
