Search for Chiral Magnetic Effects in High-Energy Nuclear Collisions

We present measurements of pion elliptic flow image in Au + Au collisions at image, as a function of event-by-event charge asymmetry image, based on data from the STAR experiment at RHIC. We find that image elliptic flow linearly increases (decreases) with charge asymmetry for most centrality bins and for all the beam energies under study. The slope parameter (r) from image difference between image and image shows a centrality dependency similar to calculations of the Chiral Magnetic Wave. The measurements of charge separation with respect to the reaction plane in search of Local Parity Violation and the Chiral Magnetic Effect are also presented for Au+Au collisions at image, and for U + U collisions at 193 GeV.
