英文摘要Measurements of two-particle correlations on transverse momentum p(t) for Au-Au collisions at root s(NN) = 130 GeV are presented. Significant large-momentum-scale correlations are observed for charged primary hadrons with 0.15 <= p(t) <= 2 GeV/c and pseudorapidity vertical bar eta vertical bar <= 1.3. Such correlations were not observed in a similar study at lower energy and are not predicted by theoretical collision models. Their direct relation to mean-p(t) fluctuations measured in the same angular acceptance is demonstrated. Positive correlations are observed for pairs of particles which have large p(t) values while negative correlations occur for pairs in which one particle has large p(t) and the other has much lower p(t). The correlation amplitudes per final state particle increase with collision centrality. The observed correlations are consistent with a scenario in which the transverse momentum of hadrons associated with initial-stage semi-hard parton scattering is dissipated by the medium to lower p(t).
