Abstract

The PHENIX experiment has acquired ∼1 billion minimum bias Au+Au events at s=200AGeV during the year 2004. This high statistics data set, coupled with a state-of-the-art analysis technique, allows for the extraction of 3D emission sources for various particle types. These 3D sources lend fresh insight into the nature of a long-range source previously reported by PHENIX. The new results indicate an anisotropic pion emission source in the pair center of mass system (PCMS) having an extended space-time extent in the outward direction. The two-proton emission source from the same data set is essentially isotropic in the PCMS. These results provide information on the evolution dynamics of the high energy density nuclear matter created at RHIC.
