Total cross-sections and the regge-pole model

Abstract

It is shown that all the available high-energy data on total cross-sections can be incorporated within the framework of the SU₃ Regge-pole model. The model consists of the exchange of tensor- and vector-meson nonets in addition to the Pomeranchuk trajectory. Some of the points which emerge from our analysis are: i) the total cross-sections of π⁺p, K⁺p, pp eventually increase towards their respective asymptotic limits, while those of their counterparts π^-p, K^-p and P^-P decrease towards their limiting values; and ii) the ratios Re/Im of the forward amplitudes are in general predicted to be large in magnitude compared to the available data.
