A Two Channel Calculation of Screening Corrections

Abstract

We present a two channel eikonal calculation in which the rescattering through a diffractive channel is included in addition to the elastic channel. Considering the spread of the experimental data, we find that we can obtain a very good description of ${\text{s}}_{tot}$, ${\text{s}}_{el}$ and $B_{el}$ in the ISR - Tevatron energy range. In this range of energy the diffractive channel, that was included in our calculation, leads to a ratio of ${\text{s}}_{SD}/{\text{s}}_{el}$ which varies between 1 and 0.5 for $20GeV\le \sqrt{s}\le 14TeV$ in agreement with the experimental data. The calculated survival probability of dijet production with a large rapidity gap is consistent with the data.
