Provides predictions for LHC and cosmic ray energies.

Estimates survival probability margins for diffractive Higgs production.

Abstract

We present and discuss our recent study of an eikonal two channel model, in which we reproduce the soft total, integrated elastic and diffractive cross sections, and the corresponding forward differential slopes in the ISR-Tevatron energy range. Our study is extended to provide predictions at the LHC and Cosmic Rays ene$ These are utilized to assess the role of unitarity at ultra high energies, as well as predict the implied survival probability of exclusive diffractiv$ central production of a light Higgs. Our approach is critically examined so as to estimate the margins of error of the calculated survival probability for diffractive Higgs production
