摘要：

We present a study of the average transverse momentum (p(t)) fluctuations and p(t) correlations for charged particles produced in Cu + Cu collisions at midrapidity for root s(NN) = 62.4 and 200 GeV. These results are compared with those published for Au + Au collisions at the same energies, to explore the system size dependence. In addition to the collision energy and system size dependence, the p(t) correlation results have been studied as functions of the collision centralities, the ranges in p(t), the pseudorapidity eta, and the azimuthal angle phi. The square root of the measured p(t) correlations when scaled by mean p(t) is found to be independent of both colliding beam energy and system size studied. Transport-based model calculations are found to have a better quantitative agreement with the measurements compared to models which incorporate only jetlike correlations.
