Testing of model predictions of forward energy flow in pp collisions at s = 7 TeV

Abstract

We simulate proton–proton collisions to calculate the energy flow with four different classes of events: hard scattering, diffractive and non-diffractive enriched interactions and inclusive minimum bias. We use cosmic ray Monte Carlo event generator to determine the energy flow for the above-mentioned classes in pseudorapidity range 1.9[Formula: see text] 4.9 at [Formula: see text] = 7 TeV in pp collisions. A comparison of model predictions to the LHCb data, obtained with the same pseudorapidity and center-of-mass energy, is presented and discussed. While predictions of the models are compatible with the experimental measurements, none of them is able to completely reproduce all the results.
