TL;DR

This paper evaluates an adjusted DPMJET-III model with chain fusion to simulate inclusive distributions in proton-proton collisions at LHC energies, comparing model predictions with experimental data across various observables.

Contribution

The study introduces energy-dependent parameter adjustments to the DPMJET-III model to improve its accuracy in simulating LHC p-p collision data.

Findings

Model reproduces charged hadron rapidity and transverse momentum distributions reasonably.

Agreement with mbda and mbdaistribution is limited.

Model captures multiplicity distributions as functions of collision energy.

Abstract

A DPMJET-III model (DPMJET-III-2011) with chain fusion adjusted to include energy.dependent parameters is used to calculate inclusive distributions in p-p collisions at LHC energies. Presented are charged hadrons rapidity distributions, transverse momentum distributions, multiplicity distributions as well as multiplicities at mid-rapidity as function of the collision energy. For hadrons with strangeness we present cms-rapidity distributions and transverse momentum distributions. With the considered merely energy-dependent adjustments the obtained agreement with the transversal \Lambda and \Xi distribution is not satisfactory.
