Femtoscopy analysis in small systems at NA61/SHINE
arXiv:2401.02553 · doi:10.1051/epjconf/202429606004
Abstract
Recent measurements of femtoscopic correlations at NA61/SHINE unravel that the shape of the particle emitting source is not Gaussian. The measurements are based on Lévy-stable symmetric sources, and we discuss the average pair transverse mass dependence of the source parameters. One of the parameters, the Lévy exponent , is of particular importance. It describes the shape of the source, which, in the vicinity of the critical point of the QCD phase diagram, may be related to the critical exponent . Its measurement hence may contribute to the search for and characterization of the critical point of the phase diagram.
