Recent measurements of the global spin polarization of $\Lambda$ hyperons further indicate the presence of strong vorticity of the rotating QGP and manifest the relativistic Barnett effect at the subatomic scale. Nevertheless, the related spin alignment phenomena of vector mesons and local spin polarization, especially in proton-nucleus collisions, cannot be simply explained by the vorticity...

discuss results for the dynamic critical exponent, the
critical behavior of transport coefficients, and the relaxation
rate of equal-time correlation functions. We also discuss
some exploratory studies of stochastic relativistic fluid

Lattice QCD based extrapolations and functional QCD methods point to a candidate critical region near T ≈ 100–120 MeV and μ_B ≈ 600–650 MeV, motivating the search for its imprint on fluctuations in heavy-ion collisions. I will first briefly review these predictions, including the latest extensions to the strangeness-neutral conditions of heavy-ion collisions. I will then discuss how to connect...

Event-by-event fluctuations, such as those of charged-particle multiplicities, mean transverse momentum and particle ratios, have been identified as sensitive observables for the study of QCD phase structure, giving access to the thermodynamics of the medium created in heavy-ion collisions and to the possible existence of a critical point. I will review the current experimental picture from...

We discuss the merits of using event generators in heavy ion physics and related systems, and give an overview of the family of JETSCAPE frameworks. We discuss recent updates and future plans regarding these event generators. We also present some recent results obtained with these frameworks, including a 3+1D Bayesian calibration of the soft sector using A+A and p+A data, a pilot study for...

One of the central open questions in heavy-ion collisions is how the initially far-from-equilibrium plasma of deconfined quarks and gluons evolves toward local thermal equilibrium, a process known as hydrodynamization. Despite its importance, direct experimental signatures of this early pre-equilibrium stage remain elusive. Hard probes, such as jets, produced at very early times, offer a...

We present a novel hydrodynamic model of nuclear collisions in which baryon number, electric charge, and strangeness diffuse as coupled currents governed by the conductivity matrix [1], using a lattice-based four-dimensional QCD equation of state. Baryon diffusion transports net baryons toward midrapidity with growing strength at lower beam energies, while net strangeness develops a wave-like...

We investigate the phase transition of QCD with three degenerate quark flavors at zero baryon chemical potential. Using Mobius domain-wall fermions as the lattice fermion formulation, we ensure excellent chiral symmetry preservation. Our simulations are performed at three different temporal lattice extents, $N_{t}=6,8,12$, with a fixed lattice spacing $a=0.1361(20)$ fm, corresponding to...

In extreme environments characterized by very high temperature and density, such as those realized in the early universe and the interior of neutron stars, a state of matter consisting of quarks and gluons, known as the quark-gluon plasma (QGP), is expected to emerge. QGP has been produced in high-energy heavy-ion collisions, enabling extensive studies of its properties. In contrast, whether...

Pietro Rescigno (RIKEN RCCS)10/22/26, 4:00 PM
Novel algorithmic developments have made it possible to perform efficient simulations of Lattice QCD at temperatures spanning up to the Electroweak scale. In this talk, I will present recent results on screening masses in several mesonic channels, for both static and non-static Matsubara sectors, obtained at 12 temperature values from 1 GeV up to 165 GeV. For each temperature, 3 or 4 lattice...

We point out a new phase structure of imaginarily rotating hot QCD: at zero quark chemical potential it has a phase in which charge conjugation $C$ is spontaneously broken and rotation alone induces an imaginary quark number density. At imaginary angular velocity $2\pi$ the existence of this phase is exact: the theory at $2\pi$ is nonrotating QCD at the Roberge-Weiss point, where $C$ is known...

QCD matter exhibits a variety of nontrivial static and dynamical phenomena under external fields. While electromagnetic fields are well-known examples, recent studies have suggested that curved spacetime can also act as an external gravitational background for quantum matter and significantly affect its phase structure.
Motivated by these developments, we address a rather fictitious but...

however, several bulk thermodynamic quantities can be expressed in terms of

José Javier Hernández Hernández (Central China Normal University)(2nd week, Oct. 19-23) QCD Matter under Extreme Conditions
Magnetic fields explicitly break the non-singlet flavour symmetry of QCD, since the light quarks carry unequal electric charges. The conventional mesonic partner relations used to diagnose chiral and $U(1)_A$ restoration at vanishing field must therefore be reconsidered before they can be applied at $eB\neq0$. We show that the neutral channels retain this diagnostic role: the splitting between...
