Survival Probability at the LHC

Abstract

Using a model based on two elements: the Good-Walker mechanism for low mass diffraction and multi-pomeron interactions for high mass diffraction, we obtain an excellent description of all aspects of soft scattering at high energy. The parameters of the model are determined by a fit to experimental data, giving the slope of pomeron to be ${\alpha }_{IP}^{\prime }\approx 0.01Ge{V}^{-2}$. We calculate the survival probability of diffractive Higgs production, and obtained a value for this observable, which is smaller than 1% for the LHC energy range.
