Abstract

An analysis of $pp$ and $p \bar{p}$ data in terms of a $K$ -matrix model for the Pomeranchuk exchange and the absorptive corrected $P^{'}$ and $ω$ Regge-pole contributions is presented. The model provides a quantitative understanding of high-energy $pp$ and $p \bar{p}$ total cross-section measurements and the measured ratio of the real to the imaginary part of the $pp$ elastic forward scattering amplitude. The structure observed in ${(\frac{d σ}{dt})}_{p \bar{p}}$ around $t = - 0.8$ Ge $V^{2}$ and in ${(\frac{d σ}{dt})}_{pp}$ at $t = - 1.2$ Ge $V^{2}$ , the shrinkage patterns in both differential cross sections, and the crossover phenomenon are explained in the framework of this model.
