MULTIPLICITY DISTRIBUTIONS IN QUANTUM CHROMODYNAMICS WITH AN INACTIVATION MECHANISM OF PARTON CASCADES

Equations of the perturbative quantum chromodynamics (PQCD) in the mod ified leading log approximation for generating functions of the multip licity distributions (GFMD) are extended by introducing the inactivati on mechanism for parton cascades. The precise form of this inactivatio n term, respecting both the tree-like structure of the PQCD and the en ergy conservation, follows from the exact analogy between the PQCD equ ations and the general nonequilibrium and the conservative fragmentati on-inactivation binary process in the limit of no inactivation The ina ctivation term of the extended PQCD for the GFMD, provides a phenomeno logical prescription to include certain aspects of hadronization in th e PQCD approach to the problem of multiplicity distributions in high-e nergy e(+)e(-) collisions.
