One of the novel anomalous chiral effects, the chiral magnetic wave (CMW), has been experimentally searched by using the charge-dependent anisotropic flow in recent years. The observed linear dependence between the charge asymmetry and the flow of the positively and negatively charged hadrons, however, still remains inconclusive owing to the existence of background effects such as local charge conservation entwined with the collectivity of the collision system.

In this poster, we present the method and the preliminary measurements of the charge asymmetry dependence of elliptic and triangular flow, as well as the corresponding three-particle correlation for charged hadrons in Pb-Pb and p-Pb collisions at the TeV energy region with the ALICE detector. The results are partly compared with that of other experiments and the theoretical estimations from the signal and background. Our measurements provide more insights into the study of CMW as well as the collective behavior of the Quark-Gluon Plasma.
