Measurement of the forward energy flow in pp collisions at sqrt{s}=7 {TeV}

Abstract

The energy flow created in pp collisions at s√=7 TeV is studied within the pseudorapidity range 1.9<η<4.9 with data collected by the LHCb experiment. The measurements are performed for inclusive minimum-bias interactions, hard scattering processes and events with an enhanced or suppressed diffractive contribution. The results are compared to predictions given by Pythia-based and cosmic-ray event generators, which provide different models of soft hadronic interactions.
