    Description
    The experimental data on multiplicity distributions is compared with QCD and hybrid NBD results. The multiparton interactions in hadron collisions are considered and the multicomponent NBD model is proposed. Its predictions for LHC are discussed. It is shown that moments of the multiplicity distribution are extremely sensitive to its shape and should be used for choice of proper model parameters. The moments for e+e- and pp are compared. The interpretation of their rank dependence and its energy behaviour is given.
