Event-by-event fluctuations in mean p(T) and mean e(T) in root s(NN)=130 GeVAu+Au collisions

2002
Distributions of event-by-event fluctuations of the mean transversemomentum and mean transverseenergy near mid-rapidity have been measured in Au+Au collisions at roots(NN)=130 GeV at the Relativistic Heavy-Ion Collider. By comparing the distributions to what is expected for statistically independent particle emission, the magnitude of nonstatistical fluctuations in mean transversemomentum is determined to be consistent with zero. Also, no significant nonrandom fluctuations in mean transverseenergy are observed. By constructing a fluctuation model with two event classes that preserve the mean and variance of the semi-inclusive p(T) or e(T) spectra, we exclude a region of fluctuations in roots(NN)=130 GeV Au+Au collisions.
