Can the Lambda pi scattering phase shifts be large?
  Motivated by the presence of nearby thresholds in other baryon-meson channels with I=1 and S=-1, we investigate whether the Lambda pi scattering phase 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 coupled-channel K-matrix approach, we find that the S-wave phase shift could be as large as -7 degrees.
