Pion femtoscopy in p + p collisions at s=200 GeV Academic Article uri icon


  • The STAR Collaboration at the BNL Relativistic Heavy Ion Collider has measured two-pion correlation functions from p+p collisions at √s=200 GeV. Spatial scales are extracted via a femtoscopic analysis of the correlations, though this analysis is complicated by the presence of strong nonfemtoscopic effects. Our results are put into the context of the world data set of femtoscopy in hadron-hadron collisions. We present the first direct comparison of femtoscopy in p+p and heavy ion collisions, under identical analysis and detector conditions. © 2011 American Physical Society.
