The study of strangeness baryon production in relativistic heavy-ion collisions provides unique insights into the properties of strongly interacting matter at extreme temperature and density. Strangeness enhancement was among the earliest proposed signatures of the formation of the quark-gluon plasma (QGP), and over the past decades, systematic measurements from SPS, RHIC, and LHC experiments...

The effect of $\Sigma^*(1385)$ baryon resonance on the time evolution of the $\Lambda$ hyperon polarization in hadronic matter is studied using a kinetic approach. This approach explicitly includes the production of the $\Sigma^*$ resonance from the $\Lambda-\pi$ and $\Sigma(1192)-\pi$ scatterings as well as its decay into $\Lambda+\pi$ or $\Sigma+\pi$. The resulting coupled kinetic...

We discuss the problem of hydrodynamics in small systems, and argue that to understand it a radical reassessment of the role of statistical fluctuations and the concept of equilibrium is necessary.

We explore the interplay between Berry curvature and topological properties in single-flavor color superconductors, where quarks form spin-one Cooper pairs. By deriving a new relation, we connect the topological nodal structure of the gap function in momentum space to the (non-Abelian) Berry flux associated with paired quarks. This generalizes the early work by Li and Haldane [1] to systems...

The Nuclotron-based Ion Collider fAcility (NICA) is a new accelerator complex currently under commissioning at JINR, designed for collisions of heavy ions and polarized particles. The Multi-Purpose Detector (MPD) experiment at NICA aims to explore the rich phase structure of QCD at finite temperature and baryon chemical potential.

J-PARC E16 and E88 experiments aim to study the in-medium modification of $\phi$ mesons in $e^+e^-$ and $K^+K^-$ decays in proton-nucleus collisions to study the effect of the chiral-symmetry restoration. In the past KEK-E325 experiment, the mass reduction of ϕ was observed at low velocity in p+Cu collisions in the $e^+e^-$ decay. E16 will measure several thousand $\phi \rightarrow e^+e^-$...

Understanding matter at high densities is one of the central goals of modern nuclear physics. Heavy-ion collisions at intermediate energies, $\sqrt{s_{NN}} = {\mathcal O}(2\;$–$\;10\;{\rm GeV})$, are the only terrestrial means to explore such extreme conditions. Several experimental programs plan to investigate this energy regime, including FAIR, NICA, HIAF, and J-PARC-HI. Before conducting...

We study how the dilepton production rates and electric conductivity are affected by the QCD critical point and phase transition to the color superconductivity. We incorporate effects of the soft modes associated with these phase transitions into the photon self-energy through the diagrams called the Aslamazov-Larkin, Maki-Thompson, and density-of-states terms, whose importance is well known...

We study the impact of the nuclear symmetry energy and its density slope parameter on the location of the neutron dripline and on neutron star properties using a semi-classical liquid drop model (LDM) in conjunction with energy density functionals constrained by chiral effective field theory. The symmetry energy at saturation density is fixed, and the surface tension parameters are optimized...

Recently we argued that baryons feel the quark substructure constraints at density around a few times the nuclear saturation density. If confinement is assumed to persist, the constraints push up the baryon momenta and make those baryons relativistic. In this talk I discuss how to derive these behaviors in a field theoretic approach, employing the phase shift representation of the...

Quark-antiquark pairs close in phase space that recombine to form a quarkonia state, also known as coalescence, are often discussed in terms of quark-gluon plasma effects on charmonia production in heavy-ion collisions. Recent LHC measurements of the charm baryon-to-meson ratios in high multiplicity p-p collisions, however, suggest coalescence as a potential hadronization mechanism. A...

The behavior of scale symmetry in dense and thermal systems is an interesting topic in nuclear physics as it relates to the stiffness of equation of state. In this talk, I will discuss the nuclear matter properties by using an effective field theory with respect to the trace anomaly of QCD. Such as the pseudoconformal structure, the behavior of sound velocity, the expectation value of the...

Two-color ($N_c=2$) QCD world is one of the useful testing grounds to delineate cold and dense QCD matter, since the lattice QCD simulation is straightforwardly applicable thanks to the disappearance of the sign problem. Motivated by recent numerical experiments from the lattice QCD activities, I am being investigating properties of dense two-color QCD by constructing the linear sigma model...

We investigate the thermodynamic properties of baryonic excitations in heavy-quark QCD. Based on a lattice QCD with $N_{\rm f}$-flavor Wilson fermions, we derive an expression for the grand potential in terms of loop operators with the hopping parameter expansion (HPE) and the cumulant expansion. Using this grand potential, we analytically compute the baryon number susceptibilities and...

QCD matter in a strong magnetic field exhibits a rich phase structure. In the presence of an external magnetic field, the chiral Lagrangian for two flavors is accompanied by the Wess-Zumino-Witten (WZW) term containing an anomalous coupling of the neutral pion $\pi^0$ to the magnetic field via the chiral anomaly. Due to this term, the ground state is inhomogeneous in the form of either a...

It was shown recently that vorticity manifesting from space-time torsion can be treated as an effective axial gauge field coupled to massless Dirac fermions in a flat spacetime. Starting from a linear sigma model, I will outline our (re)-derivation of the WZW terms in the presence of external vector, axial-vector, and pseudo-scalar fields using a derivative expansion of fermion determinants....

Compact stars serve as exceptional astrophysical laboratories for probing the properties of dense nuclear matter. Observational studies of pulsars, together with gravitational wave detections, have already imposed valuable constraints on the nuclear equation of state (EOS). Among thermodynamic quantities, the speed of sound plays a crucial role, particularly in the context of neutron star...
