摘要

The combined results from RHIC depict formation of a dense system at an energy density greater than 5GeV/fm3, well above that where hadrons exist. Statistical models reproduce the RHIC produced particle ratios indicating a temperature and baryo-chemical potential at the deconfinement phase transition boundary predicted by lattice QCD calculations. The anisotropic collective flow observed in collisions at RHIC provides direct evidence of the existence of strong pressure gradients in the highly interacting early stages of the dense medium. Hard-scattering, suppression of hadrons at large transverse momentum, and quenching of di-jets are observed in central Au + Au collisions and not in d + Au collisions, providing evidence for extreme energy loss of partons traversing the dense QCD medium created at RHIC.
