Approach to meson-baryon femtoscopy using effective field theories
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.
