Can the Lambda pi scattering phase shifts be large? art. no. 014005

Motivated by the presence of nearby thresholds in other baryon-meson channe ls with I = 1 and S = -1, we investigate whether the Lambda pi scattering p hase shifts at a center-of-mass energy equal to the Xi mass could be larger than suggested by lowest-order chiral perturbation theory. Within a couple d-channel K-matrix approach. we find that the S-wave phase shift could be a s large as -7 degrees.
