Temperature Fluctuations and Tsallis Statistics in Relativistic Heavy Ion Collisions

Abstract

AbstractWe study temperature fluctuations in the initial stages of the relativistic heavy ion collision using A Multi-Phase Transport (AMPT) model. We use the non-extensive Tsallis statistics to find the entropic index in the partonic stages of the relativistic heavy ion collisions. We find that the temperature and the entropic index have a linear relationship in the partonic stages of the collision. This is in agreement with the experimental observations in the hadronic phase. A detailed analysis of the dependence of the entropic index on the system parameters is done. Our study indicates that the entropic index can be used to study temperature fluctuations in the initial stages of heavy ion collision systemKeywordsEntropic indexTemperature fluctuationTsallis distribution
