Non-perturbative Suppression of Chiral Vortical Effect in Hot (s)QGP for Hyperons Spin Polarization in Heavy Ion Collisions

Abstract

With the Field Correlator Method (FCM) for QCD, we show that the Chiral Vortical Effect (CVE) in hot (strongly-interacting) Quark-Gluon Plasma ((s)QGP) is modified by non-perturbative interactions: by Color-Magnetic confinement, and by remnant Color-Electric interaction, which is encoded in the Polyakov line. The obtained result demonstrates numerical suppression of CVE comparable to the phenomenological suppression used for numerical simulations of RHIC-STAR data on hyperons spin polarization in non-central heavy ion collision (HIC). The parameters range in the temperature - quark chemical potential plane is expected to cover ALICE and RHIC data. The chiral current is calculated for the rigidly rotating model of (s)QGP in the linear order in angular velocity at the rotation axis with account of non-perturbative interactions.
