Proton femtoscopy at STAR

Hanna Zbroszczyk


The analysis of two-particle femtoscopy provides a powerful tool to study the properties of matter created in heavy ion collisions. Applied to identical and nonidentical hadron pairs, it makes the study of space-time evolution of the source in femtoscopic scale possible. Baryon femtoscopy allows extraction of the radii of produced sources which can be compared to those deduced from identical pion studies, providing additional information about source characteristics. In this paper we present the correlation functions obtained for protons and antiprotons for Au + Au collisions √s NN = 62.4 and 200 GeV. On the other hand, as STAR experiment participates in Beam Energy Scan program, we present theoretical predictions of p − p, \$\\textbackslash\bar p - \\textbackslash\bar p\$ and \$p - \\textbackslash\bar p\$ femtoscopic measurements, based on UrQMD simulation for √s NN = 5–39 GeV.
