Non-perturbative suppression of Chiral Effects in hot QGP for $\Lambda/\bar\Lambda$-hyperons spin polarization in heavy-ion collisions

TL;DR

This paper reviews how non-perturbative interactions in hot QCD suppress chiral effects that influence the spin polarization of hyperons in heavy-ion collisions, aligning with experimental data from LHC and RHIC.

Contribution

It introduces a non-perturbative approach using the Field Correlator Method to explain suppression of chiral effects in hot QCD relevant to hyperon polarization.

Findings

Suppression of chiral effects explained by non-perturbative interactions.

Parameter range matches LHC-ALICE and RHIC-STAR data.

Provides a theoretical framework for hyperon polarization phenomena.

Abstract

We review the calculation of suppression of Chiral Separational and Chiral Vortical Effects for strange quarks (which allegedly yield spin polarization of $\Lambda/\bar\Lambda$-hyperons in peripheral Heavy-Ion Collisions) by the non-perturbative interactions in hot deconfined QCD with the Field Correlator Method. The parameter range in the temperature-baryon density plane is expected to cover LHC-ALICE and RHIC-STAR data.
