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 more than 1.5 times in the midrapidity region and increase them about 1.5 times in the fragmentation region at the energy of LHC.

Notes

  1. Another (model dependent) possibility to estimate the contribution of the diagrams with Pomeron interaction comes [46–50] from percolation theory. The percolation approach and its previous version, the String Fusion Model [51–53] predicted the multiplicity suppression seen at RHIC energies, long before any RHIC data were taken.
