摘要：

We report charged particle pair correlation analyses in the space of Delta phi (azimuth) and Delta eta (pseudorapidity), for central Au+Au collisions at root s(NN)=200 GeV in the STAR detector. The analysis involves unlike-sign charged pairs and like-sign charged pairs, which are transformed into charge-dependent (CD) signals and charge-independent (CI) signals. We present detailed parametrizations of the data. A model featuring dense gluonic hot spots as first proposed by Van Hove predicts that the observables under investigation would have sensitivity to such a substructure should it occur, and the model also motivates selection of transverse momenta in the range 0.8 < p(t)< 2.0 GeV/c. Both CD and CI correlations of high statistical significance are observed, and possible interpretations are discussed.
