The quark constituents of the fireball created in relativistic heavy-ion
collisions carry intrinsic spin. Whether these spin degrees of freedom fully
thermalize remains an open question. Insights from kinetic theory suggest that spin
relaxes on a longer timescale compared to momentum. Polarization observables in
experiments offer valuable probes into this issue. While the assumption of...
In this talk we discuss light and heavy mesons in the frame of the local
NJL-like models and in the frame of the quark model with separable interaction
kernel. The NIL-type model is known for its ability to describe the chiral symmetry
breaking and to describe the properties of matter at finite temperature and density.
However, the description of mesons within this model is limited by the...
An overview of the
properties of an effective meson action based on the description of the QCD
vacuum in terms of a mean field corresponding to a statistical ensemble of almost
everywhere homogeneous Abelian (anti-) self-dual gluon fields represented in the
form of domain wall networks is given. Such a mean field ensures the confinement
of static and dynamic quarks and determines the...
The Spin Physics Detector (SPD) at the Nuclotron based Ion Col- lider
fAcility (NICA) is designed to study nucleon spin structure in the three dimensions.
With capabilities to collide polarized protons (up to √s = 27 GeV) and deuterons
(up to √s = 13.5 GeV) with peak design luminosity 10^{32} cm^{−2} s^{−1} for
protons (an order of magnitude less for deuterons), the experiment will...
The Multi-Purpose Detector (MPD) experiment at the NICA facility
(JINR, Dubna) will explore the high net-baryon density region of the QCD phase
diagram. Scheduled to begin operation in 2026, it will conduct heavy-ion collisions
at energies of √sNN = 4-11 GeV (collider mode) and √sNN = 2.4-3.5 GeV
(fixed-target mode). Dilepton measurements provide insights into the initial
temperature and...
Quantum chromodynamics (QCD) possesses infinitely many degenerate
vacua distinguished by winding numbers with transitions mediated by topological
gauge fields that flip helicities of quark. This induces local P and CP violation and
generates a chirality imbalance, described by a chiral chemical potential. We will
study collective oscillations of partonic degrees of freedom in such a system...
In relativistic heavy-ion collisions, Lorentz contracted pancake-shaped nuclear overlapped region evolves into a rapidly expanding approximately spherically shaped fireball. This shape change, though not topological in nature, influences the expansion dynamics, temperature evolution and lifetime of the medium. These, in turn, affect the rate of QCD topological transitions.
In this work, we...
This is important to study QCD phase diagram using ultra relativistic
heavy ion collisions. The medium created in such a collision is often of dimensions
a few fermi. An understanding of the effect of the finite volume and the boundary is
important for connecting the experimental results to the phase diagram. Using the
Nambu Jona-Lasinio model, an effective theory for the chiral transition...
