Kn scattering in the cloudy bag model : s, p and d waves

Abstract

s-, p-, and d-wave KN phase shifts are calculated with the cloudy bag model (CBM). The results are in qualitative agreement with phase-shift analysis, except in those partial waves where exotic resonances are claimed to exist. However it seems that it is possible to get good agreement for these waves by just modifying the CBM potential, without including explicitly exotic states.
