Search for DCC in Relativistic Heavy-Ion Collision Through Event Shape Analysis

Abstract

Event shape analysis has been used to look for DCC signals in simulated ultra-relativistic heavy-ion collision data at SPS energy. A simple redistribution of particles, with two detectors to detect charged particles and photons, is seen to result in the same flow direction with the flow angle difference peaking at zero. However, events where the neutral pion fraction has been modified according to the DCC probability distribution, show the flow angles in two detectors to be almost $90^o$ apart. The results presented here show that the technique is complementary to the one based on the discrete wavelet transformation. Together the techniques are seen to provide a very powerful tool for DCC search in ultra relativistic heavy ion collision.
