Approach to meson-baryon femtoscopy using effective field theories

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 ${\pi }^{+}$p and ${\pi }^{-}$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 $K_S\Lambda$ correlation functions obtained by ALICE collaboration in PbPb collisions.
