Abstract
A detailed study of energy dependence of event-by-event
pseudo-rapidity fluctuations of
the produced kaons in Au + Au collisions at
GeV in terms of the Φ
measure has been carried out in the framework of UrQMD model. The study of
event-by-event kaon fluctuation in pseudo-rapidity 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.
