Abstract

The extended R_{Ψ_m}⁽²⁾(ΔS₂) correlator is presented and examined for its efficacy to detect and characterize the quadrupole charge separation (ΔS₂) associated with the purported Chiral Magnetic Wave (CMW) produced in heavy-ion collisions. Sensitivity tests involving varying degrees of charge separation injected into events simulated with the Multi-Phase Transport Model (AMPT) show that the R_{Ψ_m}⁽²⁾(ΔS₂) correlators provide discernible responses for the background- and signal-driven quadrupole charge separation. This distinction could help identify CMW-induced quadrupole charge separation via measurements of the R_Ψ₂⁽²⁾(ΔS₂) and R_Ψ₃⁽²⁾(ΔS₂) correlators, relative to the second- (Ψ₂) and third-order (Ψ₃) event planes. The tests also indicate a sensitivity level that would allow for robust experimental characterization of possible CMW-induced charge separation.
