Gluon dominance model (GDM) studies multiparticle production in lepton and
hadron processes. It is based on the QCD and phenomenological scheme of
hadronization. The model describes well multiplicity distributions and their
moments. It has revealed an active role of gluons in multiparticle production,
it also has confirmed the fragmentation mechanism of hadronization in e+e-
annihilation and its change to recombination mechanism in hadron and nucleus
interactions. The GDM explains the shoulder structure of multiplicity
distributions. The agreement with Au+Au peripheral collisions data for
hadron-pion ratio has been also obtained with this model. Development of GDM
allows one to research the multiplicity behavior of ppbar annihilation at tens
of GeV. The mechanism of soft photons production and estimates of their
emission region have been offered. The experimental data (project
"Thermalization", U-70, IHEP) have confirmed a cluster nature of multiparticle
production.Comment: 4 pages, 4 figures, Proceedings of the ISMD06 conference, Paraty,
