Forward neutron energy spectra at s = 7TeV

Abstract

Different event generators are used to simulate proton–proton collisions at the center-of-mass energy [Formula: see text] TeV to predict the forward neutron energy spectra. The predictions from different models — DPMJETIII, Sibyll2.3c, QGSJETII-04 and EPOS-LHC — are compared with experimental data from the LHCf detector in three different regions of pseudorapidity — [Formula: see text], [Formula: see text] and [Formula: see text]. Although, the models follow tracks of the experimental data, there is a clear mismatch between the models and experimental data, and among the models as well.
