abstract
We extend the formalism for the low-energy analysis of the $\gamma p\rightarrow K^{+}\pi\Sigma$ photoproduction reaction to include the strangeness $S=-1$ meson-baryon p-wave final-state interaction with total angular momentum $J=\frac{3}{2}\,$. As an application, and a check of our method, we evaluate contributions due to the exchange of the $\Sigma^{\ast}(1385)$ resonance as derived from a chiral Lagrangian.

Femtoscopic study of the $S=-1$ meson-baryon interaction: $K^-p$, $\pi^-\Lambda$ and $K^+\Xi^-$ correlations
