Centrality and pseudorapidity dependence of charged hadron production at intermediate pT in Au+Au collisions at sNN=130GeV
PHYSICAL REVIEW C(2004)
摘要
We present STAR measurements of charged hadron production as a function of centrality in Au+Au collisions at roots(NN)=130 GeV. The measurements cover a phase space region of 0.2
更多p(T)(cut), and studied the results in the framework of participant and binary scaling. No clear evidence is observed for participant scaling of charged hadron yield in the measured p(T) region. The relative importance of hard scattering processes is investigated through binary scaling fraction of particle production.
