Pion femtoscopy in $p^+ p$ collisions at $\sqrt{s}=200$ GeV

The STAR collaboration
Phys.Rev.C 83 (2011) 064905, 2011.

Abstract (data abstract)
The STAR Collaboration at RHIC has measured two-pion correlation functions from p+p collisions at sqrt(s)=200 GeV. Spatial scales are extracted via a femtoscopic analysis of the correlations, though this analysis is complicated by the presence of strong non-femtoscopic effects. Our results are put into the context of the world dataset 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.
