Forward/backward J/ψ production and hadron vn in Cu + Au collisions in PHENIX

Cu + Au collisions provide a test for theories trying to describe heavy-ion data by changing the initial conditions and introducing distinct asymmetries into the initial geometry of the collision system. We present the first results from the PHENIX collaboration from these asymmetric collisions. The measured hadron v1 is found to be large at midrapidity, whilst v3 is found to be small when the reaction plane is determined from the spectators. In the forward region, the J/ψ is found to be more suppressed in the Cu-going direction compared to the Au-going direction.
