Title: Shear-induced anomalous transport and charge asymmetry of triangular flow in heavy-ion collisions

Abstract

Chiral anomaly implies the existence of nondissipative transport phenomena, such as the chiral magnetic effect. At second order in the derivative expansion, novel quantum transport phenomena emerge. In this paper, we focus on the anomalous transport driven by a combination of shear, vorticity, and magnetic field. We find that the corresponding transport phenomena—shear-induced chiral magnetic and chiral vortical effects—induce characteristic charge correlations among the hadrons produced in heavy ion collisions. We propose the charge asymmetry of triangular flow as a signature of the anomalous transport, and estimate the strength of the signal, as well as the background, using hydrodynamical model simulations. We find that the signal-to-background ratio for the proposed observable is favorable for experimental detection.
