The Survival Probability (S.P.) is a crucial element required to estimate the rate of production of "hard processes" e.g. central Higgs production, at the LHC. The calculation of the S.P. is dependent on the
model used to describe the "soft" processes", at high energies. We survey
several models for "soft physics", and show that it is crucial that these
models successfully describe all elastic and diffractive processes. We
present a new model, in which an excellent description of the diffractive
sector, requires contributions both from Good-Walker diffractive
processes, plus multi-Pomeron contribtions. We also discuss the rate
of production of the Higgs meson at the LHC, and the sensitivity of this
rate to the values assumed in evaluating the "hard process".
Our model predicts a value for S.P. of less that 1%, at the LHC energy.
