Description

While no P- or CP-violation has ever been observed in the strong sector of the Standard Model, there is no first principles reason for it not to be present. Theoretical calculations have shown the possibility of P-violating bubbles in the QCD vacuum, which in combination with the strong magnetic field created in off-central heavy-ion collisions leads to the Chiral Magnetic Effect (CME). In addition, a coupling between the CME and the related Chiral Separation Effect produces a wave-like excitation called the Chiral Magnetic Wave (CMW). The CMW produces a quadrupole moment that always has the same sign and is therefore present in an average over events. In this talk we present a series of charge-dependent anisotropic flow measurements in Pb-Pb collisions at $\sqrt{s_{\rm NN}} = 2.76$ TeV in ALICE. The relation of these measurements to the search for the CMW is discussed.
