We study the effect of magnetic field on particle ratios and charge fluctuations in hadron resonance gas. We argue that the big change in the pion to proton ratio is due to ill-defined description of higher-spin states, and that because of detailed balance, neutral resonances must be affected by the field too. The calculated fluctuations of conserved charges are likewise suspicious and must be...

The NA61/SHINE collaboration recently reported an excess of charged versus neutral kaons that signals an unexpectedly large breaking of the isospin symmetry. Similar excesses were also present in previous experiments, but with larger errors. Models for hadron productions in heavy ion collisions systematically underestimate the measured charge-to-neutral kaon ratio. In this talk, we report on...

The ϕ meson is a resonance particle and the lightest particle with hidden strangeness, containing both s and s̅ quarks. Strangeness enhancement is considered to be related to Quark-Gluon Plasma formation, making the ϕ meson a valuable probe due to its "double strangeness" in a partonic and zero net strangeness in a hadronic medium. Previous studies, such as EPJC 80 (2020) 199, demonstrated...

The work presented is devoted to developing the integrated hydrokinetic approach (iHKM) for relativistic nucleus-nucleus collisions. While the previous cycle of works on this topic focused on ultra-relativistic collisions at the top RHIC and different LHC energies, the current work addresses relativistic collisions at the lower energies, specifically ranging from approximately 1 to 50 GeV per...

The statistical hadronization model is known to describe very well the yields of particles produced in heavy-ion collisions at LHC, RHIC, and SPS over many orders of magnitude. Recently, we have shown [1,2] that at lower energies, not just yields but also spectra of the most abundant particles containing u and d quarks can be reproduced in the thermal model.
Strangeness, heavy compared to...

We present the first solution of (3+1)-dimensional ideal spin hydrodynamics embedded within a realistic hydrodynamic background. Using a suitable choice of initial conditions, we achieve a simultaneous description of bulk and polarization observables, successfully reproducing the correct sign of longitudinal polarization. The findings point to delayed spin thermalization, implying that...

Motivated by evidence of spin polarization in particles produced in relativistic heavy ion collisions, there is growing interest in relativistic spin hydrodynamics. In this talk, we will present the key theoretical results derived from two different approaches: covariant thermodynamics and quantum-statistical mechanics.

The azimuthal anisotropy of the final-state particles in nuclear-nuclear collisions arises from the geometry of the quark-gluon plasma fireball. In this talk, I will present flow coefficients $v_2$ and $v_3$ of charged particles measured in the Pb+Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV recorded by the ATLAS experiment in 2018. This measurement uses the scalar product and...
