KN S-WAVE PHASE SHIFTS IN A QUARK MODEL WITH GLUCON AND BOSON EXCHANGE AT THE QUARK LEVEL

摘要

The kaon-nucleon s-wave phase shifts have been calculated in a quark potential model using the resonating group method (RGM). The interquark potential includes gluon, pion and sigma exchanges. The kaon and nucleon wave functions are expanded as a sum of Gaussian functions and the Hill-Wheeler (HW) equation is solved numerically. The l = 0 phase shifts present too much attraction and in the l = 1 channel too much repulsion is obtained. [References: 14]
