Abstract

We calculate several femtoscopy correlation functions in the strangeness sectors S=0 and S=-2 for meson-baryon interactions. We combine the amplitudes of chiral perturbation theory at leading order with the TROY (T-matrix-based Routine for HadrOn femtoscopY) framework. We consider the correlation function for the π⁺p and π^-p channels, which are currently under analysis by the ALICE collaboration at the LHC. Furthermore, we will show that analogous interactions can be used to reproduce the results for K_S Λ correlation functions obtained by ALICE collaboration in PbPb collisions.
