Abstract

The vorticity-driven effects are systematically studied in various aspects. With AMPT the distributions of vorticity has been investigated in heavy ion collisions with different collision parameters. Taking the rotational polarization effect into account a generic condensate suppression mechanism is discussed and quantitatively studied with NJL model. And in chiral restored phase the chiral vortical effects would generate a new collective mode, i.e. the chiral vortical wave. Using the rotating quark-gluon plasma in heavy ion collisions as a concrete example, we show the formation of induced flavor quadrupole in QGP and estimate the elliptic flow splitting effect for Λ baryons.

Highlights

The vorticity-driven effects are systematically studied in various aspects
To extract the component of local vorticity that is truly associated with the global rotation, one needs to perform an average over the fireball
The background flow contributions to local vorticity would cancel out, and what remains can be attributed to the rotational motion

Summary

Introduction

We discuss the rotational polarization effects for quark pairings, which would change the chiral restoration and color superconductivity critical behaviors [12]. In chiral restored phase the vorticity would induce two anomalous chiral transport relations for the left and right-handed quarks respectively [13, 14]. Combining these two effects there is a new collective mode called chiral vortical wave(CVW) [15]. The CVW would reshuffle the final state hadrons’ distributions so that provide a new contribution to the elliptic flow splitting of hadrons
