Identical Particle Correlations in STAR
Abstract
Preliminary results of identical-particle correlations probing the geometric substructure of the particle-emitting source at RHIC are presented. An -independent scaling of pion HBT radii from large (central Au+Au) to small (p+p) collision systems naively suggests comparable flow strength in all of them. Multidimensional correlation functions are studied in detail using a spherical decomposition method. In the light systems, the presence of significant long-range non-femtoscopic correlations complicates the extraction of HBT radii.
