| Abstract | We present the result of the femtoscopic analysis of non-identical charged kaon correlations in Pb-Pb collisions at $\sqrt{s_{NN}}$ = 2,76 TeV obtained in ALICE at the LHC. One-dimensional K+K− correlation functions were analyzed in three centrality classes and eight transverse momentum ranges. The femtoscopic correlations of K+K− pairs are the result of Coulomb final-state interactions and formation of a0(980) and f0(980) resonances. The K+K− correlation function was fit with the R. Lednicky and V. Luboshitz model [1]. For the first time, f0(980) mass and couplings were extracted from the K+K− correlation functions fit with the constraint on the radii to be close to the corresponding radii from identical charged kaon correlations. |
