Femtoscopy in PHENIX: Evidence for a Long Range Structure in the Pion Emission Source in Au+Au Collisions at RHIC
The PHENIX experiment has acquired {approx}1 billion minimum bias Au+Au events at {radical}(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.more »
