Meson-Baryon and Baryon-Baryon Scattering in ReggeizedU(6)⊗U(6)Theory

Abstract

A complete set of rules is presented for evaluating the master meson-trajectory exchange contribution to high-energy scattering between mesons ($M$) and baryons ($B$) in $U\left(6\right)\mathrm{}\otimes U\left(6\right)\mathrm{}$ theory. The practical implementation of these rules is illustrated in considerable detail for quark-quark scattering as well as for the ${35}_W$-exchange contribution to $\mathrm{MB}$ and $\mathrm{BB}$ charge-exchange amplitudes.
