KN phase shifts in a constituent quark model

In a first step, the I = 1 and I = 0 kaon-nucleon s-wave phase shifts have been calculated in a quark potential model using the resonating group metho d (RGM) and a relativistic kinematics. The spinless Salpeter equation has b een solved numerically using the Fourier grid hamiltonian method. The resul ts have been compared to the nonrelativistic ones. For each isospin channel the phase shifts obtained are not so far from the nonrelativistic results. Then, K-nucleon p, d, f, g-waves phase shifts have been calculated using a nonrelativistic kinematics. (C) 2001 Elsevier Science B.V. All rights rese rved.
