摘要
Event-by-event fluctuations of the average transverse momentum of produced particles near midrapidity have been measured by the PHENIX Collaboration in roots(NN)=200 GeV Au+Au, and p+p collisions at the Relativistic Heavy Ion Collider. The fluctuations are observed to be in excess of the expectation for statistically independent particle emission for all centralities. The excess fluctuations exhibit a dependence on both the centrality of the collision and on the p(T) range over which the average is calculated. Both the centrality and p(T) dependence can be well reproduced by a simulation of random particle production with the addition of contributions from hard-scattering processes.
