- Abstract
The three-dimensional femtoscopic correlations of pion and kaons are presented for Pb–Pb collisions at s NN = 5.02 TeV within the framework of (3+1)D viscous hydrodynamics combined with THERMINATOR 2 code for statistical hadronization. The femtoscopic radii for pions and kaons are obtained as a function of pair transverse momentum and centrality in all three pair directions. The radii showed a decreasing trend with an increase of pair transverse momentum and transverse mass. for all centralities. These observations indicate the presence of strong collectivity. A simple effective scaling of radii with pair transverse mass in the model (without hadron cascade stage) was observed for both pion and kaons.
