Within the framework of the exploration of the phase diagram of nuclear matter, the susceptibilities are useful tools to probe the existence of a 1st order phase transition and a possible critical endpoint. In this context, STAR collaboration recently published some results of variances and 2nd order susceptibility ratios for electric charge (Q), protons and kaons (the last 2 being used as...
The development of the merged EPOS+PHSD approach is one way to study the influence of the initial non-equilibrium stage of the heavy-ion reactions on the final observables. The microscopic understanding of the initial phase of heavy-ion collisions is an intricate problem, in this respect, the EPOS and PHSD approaches provide a unique possibility to address this problem. We employ the EPOS to...
Parton-Hadron-Quantum-Molecular-Dynamics (PHQMD) is, a microscopic n-body
transport model based on the QMD propagation of the baryonic degrees of freedom with density
dependent 2-body potential interactions. All other ingredients of PHQMD, including the collision
integral and the treatment of the quark-gluon plasma (QGP) phase, are adopted from the Parton-
Hadron-String Dynamics (PHSD)...
Baryon resonances (3-quark states) occurred in the micro-second old universe during the transition between the Quark Gluon Plasma and the confinement of quarks and gluons in nucleons. Their properties (mass, life time, branching ratios,…) can be determined through nucleon excitations using electron, photon or hadron beams, providing a unique source of information on Quantum ChromoDynamics...
ALICE is one of the experiments of the LHC (Large Hadron Collider) at CERN (European Organization for Nuclear Research). The purpose of ALICE (A Large Ion Collider Experiment) is to study the properties of strongly interacting matter by performing different kinds of measurements in proton-proton, proton-nucleus and nucleus-nucleus collisions. The first detector encountered by collisions'...
Lattice QCD predicts the formation of the quark-gluon plasma (QGP) at extreme conditions of temperature and energy density, a state of matter where quarks and gluons are no longer
confined inside hadrons. The study of QGP is carried out by different experiments, e.g ALICE experiment, at the large hadron collider (LHC), where two ultra relativistic beams of proton or heavy ions are collided...
Quarkonium production in small systems has been the subject of many theoretical and experimental studies. In proton--nucleus (p--A) collisions, their production is sensitive to cold nuclear matter effects such as nuclear modification of parton densities, parton energy loss via initial-state radiation and transverse momentum broadening due to multiple soft collisions. Furthermore,...
Ultra-relativistic heavy-ion collisions are an important tool to investigate the Quark-Gluon Plasma predicted by the theory of Quantum Chromo-Dynamics. It is also possible to use these collisions to study poorly known gluon shadowing effects at low Bjorken-$x$ values. Indeed Ultra-Peripheral Collisions (UPC) between two Pb nuclei, in which the impact parameter is larger than the sum of their...
