Abstract
Parity-odd domains from QCD are predicted to cause charge separation of quarks across the reaction plane created in non-central relativistic heavy-ion collisions—the chiral magnetic effect. Here, we present several measurements to search for charge separation across the reaction plane at STAR. We use three different observables: a three-point correlator, a multiplicity asymmetry correlator as well as a reaction-plane-dependent balance function. The correlations are studied differentially and are presented for several Au+Au collision energies: 200, 62.4, 39, 11.5 and 7.7 GeV. We will discuss the sensitivities of these latest measurements to possible parity odd signals and parity even backgrounds.
