Abstract
The azimuthal correlator Ay searching for the chiral magnetic effect (CME) is contaminated by a major background proportional to the elliptic flow v2. Event-shape engineering (ESE) and event-shape selection (ESS) binning events in dynamical and statistical fluctuations of v2, respectively, are two methods searching for the CME. We conduct a systematic study using physics and toy model simulations. It is found that ESE fulfills the general premise of measuring the CME but is statistically hungry, whereas ESS is not practical to measure the CME because of the intertwining variables used in the method.
