Description
Experiments conducted in the last decade to search for the Chiral Magnetic Effect (CME) in heavy-ion collisions have been inconclusive. Isobar program at RHIC was conducted to address this problem. Also, in order to study the CME, a new approach known as the Sliding Dumbbell Method (SDM) [1] has been developed. This method searches for the back-to-back charge separation on an event-by-event basis. The SDM facilitates the selection of events corresponding to various charge separations ($f_{DbCS}$) across the dumbbell. A partitioning of the charge separation distributions for each collision centrality into ten percentile bins is done in order to find potential CME-like events that correspond to the highest charge separation across the dumbbell. Results for two- and three-particle correlators for isobar (Ru+Ru and Zr+Zr) collisions at $\sqrt{s_{\mathrm{NN}}} = 200$ GeV will be presented for each bin of $f_{DbCS}$ in each collision centrality. The background contribution due to statistical fluctuations is obtained by randomly shuffling the charges of the particles in a particular collision centrality. Correlated backgrounds are calculated for each $f_{DbCS}$ bin of charged shuffled events using their corresponding original events.
