Energy dependence of event-by-event kaon fluctuation in Au plus Au collisions at=19.6-200 GeV-a simulated study

摘要

A detailed study of energy dependence of event-by-event pseudorapidity fluctuations of the produced kaons in Au + Au collisions at = 19.6-200 GeV in terms of the I broken vertical bar measure has been carried out in the framework of the UrQMD model. The study of event-by-event kaon fluctuation in pseudorapidity space reveals energy dependence. It has been seen that as energy increases event-by-event fluctuation increases for both positive and negative kaons. Moreover, the positive kaons show larger event-by-event fluctuations than the negative kaons.
