Pion-Kaon Correlations in Central Au + Au Collisions at SNN= 130 GeV uri icon

abstract

  • 2003 The American Physical Society. Pion-kaon correlation functions are constructed from central Au + Au STAR data taken at sNN = 130 GeV by the STAR detector at the Relativistic Heavy Ion Collider (RHIC). The results suggest that pions and kaons are not emitted at the same average space-time point. Space-momentum correlations, i.e., transverse flow, lead to a space-time emission asymmetry of pions and kaons that is consistent with the data. This result provides new independent evidence that the system created at RHIC undergoes a collective transverse expansion.
