Particle multiplicities at energies available at the CERN Large Hadron Collider (LHC) and deviations from limiting fragmentation

The pseudorapidity density of charged particles produced at collisions at energies available at the CERN Large Hadron Collider (LHC) are predicted by using two complementary production mechanisms with a set of consistent integrated and unintegrated parton distributions. We discuss the limiting fragmentation hypothesis and its possible violation, and we compare our model with other partonic models.
