Scaling Properties of the $\Delta \gamma$ Correlator: Constraints on Background and CME-Sensitive Charge Separation in Heavy-Ion Collisions

Roy A. Lacey, Niseem Magdy

The scaling properties of the $\Delta \gamma$ correlator are used to investigate charge separation associated with the chiral magnetic effect (CME) in $p$+Au, $d$+Au, Ru+Ru, Zr+Zr, and Au+Au…
