Description
To probe the Chiral Magnetic Effect (CME) in heavy-ion collisions, a new technique, Sliding Dumbbell Method (SDM) [1] is developed to search for the back-to-back charge separation on event-by-event basis. The SDM helps in selecting the events corresponding to different charge separations ($f_{DbCS}$). The charge separation distributions for each collision centrality is divided into 10 percentile bins to select potential CME-like events corresponding to the maximum charge separation (e.g. top 10$\%$) in a given collision centrality. Results will be discussed for two- and three-particle correlators with respect to each bin of $f_{DbCS}$ for each collision centrality for isobaric and Au$+$Au collisions at $\sqrt{s_\mathrm{NN}} = 200$ GeV. The background contribution due to statistical fluctuations is obtained by shuffling the charges of particles in a given collision centrality. The correlated background amongst the produced particles which got removed due to shuffling is determined by restoring the shuffled charges.
