The Chiral Magnetic Effect: Beam-energy and system-size dependence

Abstract

We consider the energy dependence of the local $\mathcal{P}$ and $\mathcal{C}\mathcal{P}$ violation in Au+Au and Cu+Cu collisions over a large energy range within a simple phenomenological model. It is expected that at LHC the chiral magnetic effect will be about 20 times weaker than at RHIC. At lower energy range this effect should vanish sharply at energy somewhere above the top SPS one. To elucidate CME background effects a transport model including magnetic field evolution is put forward.
