Abstract
In a noncentral heavy-ion collision, the two colliding nuclei have a finite angular momentum in the direction perpendicular to the reaction plane. After the collision, a fraction of the total angular momentum is retained in the produced hot quark-gluon matter and is manifested in the form of fluid shear. Such fluid shear creates finite flow vorticity. We study some features of such generated vorticity, including its strength, beam energy dependence, centrality dependence, and spatial distribution.
Highlights
Relativistic heavy-ion collisions provide us the environments in which we can study the strongly interacting matter under unusual conditions, like extremely high temperature [1] and extremely strong magnetic field [2, 3]
A fraction of the total angular momentum is retained in the produced partonic matter which we will call the quark-gluon plasma (QGP)
We present detailed numerical study of the event-by-event generation of vorticity in heavy-ion collisions by using the HIJING event generator [7]
Summary
Relativistic heavy-ion collisions provide us the environments in which we can study the strongly interacting matter under unusual conditions, like extremely high temperature [1] and extremely strong magnetic field [2, 3]. 1. Introduction Relativistic heavy-ion collisions provide us the environments in which we can study the strongly interacting matter under unusual conditions, like extremely high temperature [1] and extremely strong magnetic field [2, 3]. It was realized that noncentral heavy-ion collisions can generate finite flow voriticty and provide us a chance to study quark-gluon matter under local rotation [4, 5, 6, 7].
