Abstract
In non-central relativistic heavy ion collisions, \(\mathcal{P}\)-odd domains, which might be created in the process of the collision, are predicted to lead to charge separation along the system orbital momentum [1]. An observable, \(\mathcal{P}\)-even, but directly sensitive to the charge separation effect, has been proposed in Ref. [2] and is based on 3-particle mixed harmonics azimuthal correlations. We report the STAR measurements using this observable for Au+Au and Cu+Cu collisions at \(\sqrt {s_{NN} } \) = 200 and 62 GeV. The results are reported as function of collision centrality, particle separation in rapidity, and particle transverse momentum. Effects that are not related to parity violation but might contribute to the signal are discussed.
