Levy HBT results at NA61/SHINE

Abstract

Bose-Einstein (or HBT) momentum correlations reveal the space-time structure of the particle emitting source created in high energy nucleus-nucleus collisions. In this paper we present the latest NA61/SHINE measurements of Bose-Einstein correlations of identified pion pairs and their description based on Levy distributed sources in Be+Be collisions at 150A GeV/c. We investigate the transverse mass dependence of the Levy source parameters and discuss their possible interpretations.
