Abstract
We argue that the mean transverse momentum of particles produced in very high energy nucleus-nucleus collisions or in very high multiplicity pp collisions may be directly related to the energy per unit entropy of the hot matter originally formed. We also argue that the initial energy density is related to the mean transverse momentum and to the rapidity density of pions. A tentative analysis of cosmic ray data, and of pp collider data finds support for the conjecture that the matter produced in such collisions undergoes a phase transition from a hadron gas to a quark-gluon plasma.
