Description
A charge-sensitive correlator R$(\Delta S)$ is used to detect and characterize charge separation associated with the Chiral Magnetic Effect (CME) in heavy-ion collisions. The correlator gives a concave-shaped response relative to the second-order event plane, $\Psi_2$, and a null response relative to the third-order plane, $\Psi_3$, for CME-driven charge separation~[1].
We will present and discuss R$(\Delta S)$ measurements, relative to $\Psi_2$ and $\Psi_3$, for collisions of Au+Au at $\sqrt{s_{NN}}$= 200, 39, 27 and 19.6 GeV, U+U at $\sqrt{s_{NN}}$= 193 GeV, and Cu+Au, Cu+Cu, d+Au and p+Au at $\sqrt{s_{NN}}$=200 GeV. Measurements for a broad range of transverse momentum, pseudorapidity, and centrality intervals, will be presented and compared to results from the Anomalous Viscous Fluid Dynamics model [2].
