Production of secondaries in soft p+pb collisions at LHC

TL;DR

This paper models secondary particle production in soft proton-lead collisions at LHC energies using the Quark-Gluon String Model, highlighting significant inelastic screening effects that alter spectra across rapidity regions.

Contribution

It introduces inelastic screening corrections into the Quark-Gluon String Model for p+Pb collisions at LHC energies, providing more accurate predictions of secondary spectra.

Findings

Inelastic screening reduces midrapidity spectra by about 3 times.

Spectra increase by about 2 times in the fragmentation region.

Screening effects are very significant at LHC energies.

Abstract

We calculate the inclusive spectra of secondaries produced in soft (minimum bias) p+Pb collisions in the framework of Quark-Gluon String Model at LHC energy, and by taking into account the inelastic screening corrections (percolation effects). The role of these effects is expected to be very large at very high energies, and they should decrease the spectra about 3 times in the midrapidity region and increase them about 2 times in the fragmentation region at the energy of LHC.
