The multiplicity distribution is described in terms of models incorporating the stochastic branching of quarks and gluons, along with fluctuations in their production. Results show a reasonable description of charged-particle multiplicity distributions measured in pp collisions by the CMS collaboration at centre-of-mass collision energies of 0.9, 2.36, and 7 TeV for |η| < 0.5, 1.0, 1.5, 2.0, and 2.4. A prediction for 13 TeV is also given.
