Abstract

The energy flow created in pp collisions at root s = 7 TeV is studied within the pseudorapidity range 1.9 <eta <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.
