Abstract

The total cross-sections of various MM, MB, BB and B {Mathematical expression} processes calculated by Horwitz and Rosner using the CHKN fit are expanded in terms of the imaginary parts of the forward elastic direct-channel amplitudes with SU₃ Clebsch-Gordan coefficients. It is consistent to assume that the energy-dependent parts of the amplitudes are SU₃ invariant, while the SU₃ violating parts are essentially constant background contributions. The changes of the s-channel amplitudes in energy are calculated; the results are consistent with what would be expected from considerations of duality.
