30. Few-gluon interactions in high energy nuclear collisions

Thomas Trainor

1. Hot and Dense QCD Matter

Oral presentation

A conventional narrative developed for high energy heavy ion collisions prior to the RHIC program assumed hadron production dominated by hot and dense QGP formation, expansion and freezeout. Proposed diagnostics included detection of elliptic and radial flows via correlation and spectrum analysis and jet quenching in a dense medium via rescaled spectrum ratios. The validity of that narrative...

24. Multi-charge QCD equation of state with a critical surface

1. Hot and Dense QCD Matter

Oral presentation

The equation of state characterizes the properties of QCD matter created in high-energy nuclear collisions. One of the important goals in nuclear physics is to search for the critical point, which is speculated to exist at finite baryon density. This is a major objective of the beam energy scan programs at the BNL Relativistic Heavy Ion Collider. In this work, we incorporate such a structure...

9. Anomalous dynamical screening of relativistic plasma in a magnetic field

Dr Sota Hanai (Academia Sinica)

1. Hot and Dense QCD Matter

Oral presentation

Understanding the response of relativistic plasmas is important for elucidating high-energy systems such as neutron stars, the early Universe, and heavy-ion collisions. In these systems, the chirality of fermions is known to induce non-trivial transport phenomena.
Motivated by this, we study electromagnetic collective excitations in magnetized relativistic plasmas, taking the chiral charge...

5. Local spin polarization by color-field correlators and momentum anisotropy

Haesom Sung

1. Hot and Dense QCD Matter

Oral presentation

We study the local spin polarization of quarks induced by color-field correlators stemming from the correlation of chromo-Lorentz force and chromo-magnetic polarization or chromo-spin Hall effect in the presence of momentum anisotropy. Such effects can trigger longitudinal polarization from fluctuating color fields in glasma or quark gluon plasma phases with transverse expansion for...

13. A novel higher-harmonic observable for the chiral magnetic effect in heavy-ion collisions

Han-Sheng Li

17/08/2026, 10:40

1. Hot and Dense QCD Matter

Oral presentation

The chiral magnetic effect (CME) is a phenomenon in which electric charge is separated by a strong magnetic field from local domains of chirality imbalance in quantum chromodynamics. The CME-sensitive azimuthal correlator difference $\Delta\gamma$ between opposite- and same-sign charged hadron pairs is designed to detect charge separation along the magnetic field, on average perpendicular to...

59. Exploring the Interplay of Inhomogeneity, First-Order Phase Transition, and the QCD Critical Point at Finite Density (flash talk)

Chiho Nonaka

1. Hot and Dense QCD Matter

Poster presentation

Understanding the finite-density QCD phase diagram requires clarifying the relationship between inhomogeneous matter, the first-order phase transition, and the QCD critical point. In this work, we perform JAM2 simulations of heavy-ion collisions in the RHIC Beam Energy Scan energy region and analyze HBT and two-particle correlation observables. The goal is to investigate how possible spatial...
