Femtoscopic correlation measurement with symmetric Lévy-type source at NA61/SHINE

Abstract

Measuring quantum-statistical, femtoscopic (including final state interactions) momentum correlations with final state interactions in high-energy nucleus-nucleus collisions reveal the space-time structure of the particle-emitting source created. In this paper, we report NA61/SHINE measurements of femtoscopic correlations of identified pion pairs and describe said correlations based on symmetric Lévy-type sources in Ar+Sc collisions at 150A GeV/c. We investigate the transverse mass dependence of the Lévy-type source parameters and discuss their possible interpretations.
