The title and abstract are enclosed below. | | Best regards, | | Bill | | ------------------------------------------------------------------------------------------- | Title: Measurement of Non-Random Event-by-Event Fluctuations of Average | Transverse Momentum in sqrt(s_NN)=200 GeV Au+Au and p+p Collisions. | | Abstract: | | Event-by-event fluctuations of the average transverse momentum of | produced particles near mid-rapidity have been measured by the PHENIX Collaboration in | sqrt(s_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 transverse momentum window over | which the average is calculated. This behavior is consistent with a | scenario whereby the predominant contribution to the excess is due to | jets where the high transverse momentum hadron production is suppressed | in the most central collisions. |
