Diffractive processes at the LHC.

Abstract

We present a model of high energy soft pp interactions that has multi s‐ and t‐channel components, which has been tuned to describe all the available data. The t‐channel components allow matching of the soft to the hard (QCD) Pomeron. Absorptive effects are found to be large, and, for example, suppress the prediction of the total pp cross section to about 90 mb at the LHC. We use the model to calculate the survival probability, S2,S2, of the rapidity gaps in the exclusive process pp→p+H+p,pp→p+H+p, a process with great advantages for searching for the H→bb̄H→bb̄ signal. We consider both eikonal and enhanced rescattering.
