Abstract

We have calculated the femtoscopic correlation functions of meson-baryon pairs in the strangeness S=-1 sector, employing a unitarized chiral interaction model up to next-to-leading order. We will show preliminary results for the π^-Λ correlation function, which is presently under analysis by the ALICE@LHC collaboration. We will also demonstrate that, within 2σ, the employed interaction is perfectly capable of reproducing the K^-p correlation function data measured by the same collaboration, without the need of changing the coupled-channel interactions, as has been suggested recently.
