Prof. Mikhail Zubkov (Ariel University, Israel)27/08/2024, 10:00Heavy Ion Collisions and Critical PhenomenaTalk
We consider macroscopic motion of quantum field systems. The Zubarev statistical operator allows us to describe several types of motion of such systems in thermal equilibrium. We formulate the corresponding effective theory on the language of a functional integral. The effective Lagrangian is calculated explicitly for the fermionic systems interacting with dynamical gauge fields. Possible...

One of the most important question in modern nuclear physics is what kind of matter phases are realised in dense QCD. While there have been many studies of spatially homogeneous matter phases, inhomogeneous chiral condensed phases have attracted much attention in recent years. One of these inhomogeneous chiral condensed phases is the dual chiral density wave (DCDW) phase, in which both scalar...

Recently, a large amount of experimental data has been collected in high-energy physics for studying the properties of nuclear matter. The main interest is to study the phase diagram and localize phase transitions from hadronic to the quark-gluonic matter. There are different technics to study the hot matter. One of these is femtoscopy, which uses two-particle correlations to extract...

Identified hadron production has long played an important role in studying the final state effects of relativistic ion collisions and the details of hadronization processes. The studies of various observables in both small and large collision systems are crucial to investigate the dependence of various quark gluon plasma and hadronization properties and the observability of final state effects...

sPHENIX is a new experiment at the Relativistic Heavy Ion Collider (RHIC), designed with large-acceptance, hermetic EM and hadronic calorimeters. One of the main goals of the sPHENIX experiments is the measurement of jets and their substructure in heavy ion collisions as a probe of the QGP at RHIC. Since jets in heavy ion collisions sit on top of large fluctuating backgrounds, these must be...

Quark-gluon plasma (QGP) matter is created in heavy-ion collisions at relativistic speeds. The $\phi$-meson ($s\bar{s})$ produced during heavy-ion collisions is expected to have a small hadronic interaction cross-section and thus retain information from the early stages of the QGP medium. Therefore, the study of strangeness production and collectivity plays a significant role in understanding...

The Zubarev approach of the non-equilibrium statistical operator [1] is used to account for the enhancement of the low-$p_T$ part of pion spectra by introducing an effective pion chemical potential [2]. This is an alternative to the explanation of the low-$p_T$ enhancement by resonance decays. We report on the first results obtained with a newly developed thermal particle generator that...

The NA61/SHINE experiment, situated at the CERN SPS, serves as a versatile fixed-target facility dedicated to probing the phase diagram of strongly interacting matter. Utilizing a unique two-dimensional scan in collision energy (sqrt(s_NN) = 5.1 - 16.8/17.3 GeV) and system size, the NA61/SHINE experiment aims to elucidate the onset of deconfinement and characterize the properties of the...

The Fourier harmonics, $v_2$ and $v_3$ of negative pions are measured at center-of-mass energy per nucleon pair of $\sqrt{s_{\mathrm{NN}}}$= 17.3 GeV around midrapidity by the CERES/NA45 experiment at the CERN SPS in 0--30\% central PbAu collisions with a mean centrality of 5.5\%. The analysis is performed in two centrality bins as a function of the transverse momentum...

The sPHENIX detector is the first new detector constructed at the Relativistic Heavy-Ion Collider (RHIC) in twenty years, featuring cutting-edge calorimeter, tracking, and forward detectors designed to investigate the properties and behavior of the strongly coupled Quark Gluon Plasma (QGP) generated in heavy-ion collisions. The sPHENIX detector at RHIC offers new capabilities for studying ...

Heavy-ion collisions with the RHIC Beam Energy Scan II (BES-II) program at STAR provided a unique opportunity to explore the QCD phase diagram at finite baryon density. Conserved charge fluctuations are believed to be sensitive to the QCD phase structure. In this talk, we will present the recent STAR highlights on fluctuation studies in search of the critical endpoint in QCD phase transition...

Our objective is to test published models of partonic energy loss, particularly those describing the energy loss mechanisms of quarks traversing nuclear matter, within the framework of semi-inclusive deep inelastic scattering. Our methodological approach focuses on quantifying quark energy loss in cold matter by analyzing positive pions ($\pi^{+}$) produced in various nuclear targets,...

Due to the perturbative and non-perturbative regimes involved, the quarkonia (i.e., bound states of a heavy charm or bottom quark and its antiquark) production in hadronic collisions provides a unique testing ground for understanding quantum chromodynamics (QCD). In addition, quarkonia represent an important tool to investigate the properties of the strongly interacting medium produced in...

The PHENIX experiment measured the centrality dependence of two-pion Bose-Einstein correlation functions in sqrt(s(NN))= 200 GeV Au+Au collisions at the Relativistic Heavy Ion Collider at Brookhaven National Laboratory. The data are well represented by Lรฉvy-stable source distributions. The extracted source parameters are the correlation-strength parameter $\lambda$, the Lรฉvy index of...

Fluid-dynamical modelling of heavy-ion collisions in the region of RHIC Beam Energy Scan (BES) and FAIR experiments poses notable challenges. Contraction of the incoming nuclei is much weaker, which results in a long inter-penetration phase and a complex initial-state geometry. Conventional hydrodynamic models, where the fluid phase starts at a fixed proper time ฯ0, therefore miss the...

The STAR experiment at RHIC studies Quantum Chromodynamics (QCD) via relativistic heavy ion collisions. Anisotropic flow are sensitive to the initial geometry and expansion dynamics in heavy-ion collisions, and are a valuable probe to study the Equation of State of the produced matter. Global angular momentum and anisotropic flow each can generate vorticity in QCD matter produced in heavy-ion...

LHC is planning to collect oxygen-oxygen ($O+O$) data at a center-of-mass energy of $\sqrt{s_{\mathrm{NN}}}$ = 7 TeV in order to investigate the particle production mechanisms and associated observables.

Jets originating from hard-scattered partons in the early stages of heavy-ion collisions travel through the Quark Gluon Plasma (QGP) and are modified or quenched relative to a $p$+$p$ collision baseline. Jet quenching studies have evolved rapidly from measuring modification of jet-production cross-sections in heavy-ion collisions to probing jet substructure. Jet substructure measurements...

Particle spectra of the hadrons produced during high-energy collisions have a power-law tail, and there are many studies showing that the distribution of the hadrons can be described using the quasi-exponential distribution derived from the non-additive (a.k.a. non-extensive) statistical mechanics proposed by C. Tsallis. Such a power-law behaviour can arise in systems (e.g. the Quark-Gluon...

The chiral imbalance, coupled with the presence of a strong magnetic field produced during heavy-ion collisions, results in charge separation along the magnetic field axis, a phenomenon known as the Chiral Magnetic Effect (CME). A novel technique, the Sliding Dumbbell Method (SDM) [1, 2] has been developed to investigate the CME with the RHIC's isobar program. The SDM facilitates the selection...
