NA61/SHINE Levy HBT measurements in Be+Be collisions at 150A GeV/c

The program of NA61/SHINE allows for the investigation of the phase diagram of strongly interacting matter. The nature of the quark-hadron transition can be studied through analyzing the space-time structure of the hadron emission source via the measurement of Bose-Einstein momentum correlations. These can be described by correlation functions based on Lévy-distributed sources. This report presents the performance plots of Bose-Einstein correlation analysis in Be+Be collisions at 150A GeV/c beam momentum. The transverse mass dependence of the Lévy source parameters and their possible interpretations are discussed.
