Quark gluon plasma and multiplicity dependence of transverse momentum in hadronic collisions

Abstract

I propose experimental tests to examine the origin of the average <p T > dependence on hadron-hadron events multiplicity and to verify some possible implications of the existence of high-temperature phase transition to quark-gluon plasma. I suggest that evidences may already exist of this transition in SPS collider and ISR events with central rapidity density dn/dy within an interval of one or two units around 6.
