Abstract:
It was recently shown by Teaney and Yan that fluctuations in the initial geometry of a heavy ion collision generally result in a dipole asymmetry of the distribution of outgoing particles. This asymmetry, unlike the usual directed flow, is expected to be present at a wide range of rapidity -- including midrapidity. We show that first evidence of this phenomenon can be seen in recent two-particle correlation data by STAR, and propose a new direct measurement.
