Global polarization and parity violation study in Au+Au collisions

We present results on the parity violation effects and global system polarization measurements in Au+Au collisions at sqrt(s_NN) = 62 GeV obtained with the STAR detector at RHIC. The parity violation effects are studied by three particle azimuthal correlations of charged particles. The global polarization of the system is examined by measuring the polarization of strange hyperons with respect to the collision reaction plane.
