Total and inelastic cross-sections at LHC at CM energy of 7 TeV and beyond

Abstract

We discuss expectations for the total and inelastic cross-sections at LHC CM energies $\sqrt{s}=7TeV$ {and $14TeV$} obtained in an eikonal minijet model augmented by soft gluon $k_t$-resummation, which we describe in some detail. We present a band of predictions which encompass recent LHC data and suggest that the inelastic cross-section described by two channel eikonal models include only uncorrelated processes. We show that this interpretation of the model is supported by the LHC data.
