Quark compound bag model applied to KN interaction

The quark compound bag (QCB) model was applied to S-wave KN scattering with spin of I=0 and I=1. The good description of KN amplitudes is obtained in the wide interval of energies. The resulting parameters of KN potential are shown to coincide with the parameters obtained from the explicit form of nonlocal and energy dependent QCB potential. The values of energies of QCB states agree with MIT bag predictions
