  The collective behavior of secondary particles in pp - interactions at 70
GeV/c is studied. A Two Stage Gluon Model is offered to describe proceses with
very high multiplicity. An active role of gluons is shown in multiparticle
dynamics. The analysis of multiplicity distributions has revealed a possibility
of a thermodynamic interpretation of these interactions. A mechanism of the
soft photon production as a signature of the quark-gluon system is proposed.
