Abstract
The gamma -analogy hypotheses for Reggeon couplings are used to predict the dominant P, f, omega , rho and A2 exchanges in pi +or-p, K+or-p, pp and pp elastic scattering. The couplings are all determined by the vector-meson-photon couplings fomega gamma and frho gamma , with only a small allowance for f- omega degeneracy breaking. Then the only unknown is the P:f ratio. When this has been determined (as a function of t) the authors can predict successfully sigma tot and d sigma /dt for all the above processes, and make reasonable estimates of the decay rates for rho , f, g, h to pi pi and f, A2, omega *, g, h to KK.
