S-wave phase shift in Lambda-pi scattering

Abstract

We calculate the s-wave strong interaction $\Lambda$$\pi$ phase shift at the $\Xi$ mass taking into account contributions from the ${\frac{1}{2}}^{-}$ and ${\frac{3}{2}}^{-}$ $\Sigma$ resonances. We find the S-wave phase shift to be small, of the order of 0.3 degrees and bounded by 0.5 degrees.
