Preserved Fulltext
Crossing matrices are derived for meson-baryon scattering in SU(4). Using the Clebsh-Gordan coefficients and crossing matrices, a crossing invariant solution of baryon exchange degeneracy is found within the framework of SU(4) and no exotics in all channels. SU ( 4) symmetry, which will be useful for a future analysis of the quartet model. For completeness and to demonstrate how to handle some relations, \Ve derive in this paper crossing matrices for meson-baryon scattering amplitudes in § 2. In
