Abstract: QCD equations for the generating functions are applied to separate soft and hard jets in e + e − processes of multiparticle production. The dependence of average multiplicities and higher moments of multiplicity distributions of particles created in “newly born” soft subjets on the share of energy devoted to them is calculated in fixed coupling gluodynamics. This dependence is the same as for the total multiplicity up to a constant factor if soft jets are defined as those carrying out a fixed share of initial energy at all energies. The constant factor depends on this share in a nontrivial way. Other definitions are also proposed. The relation between these quantities for soft and hard processes is discussed.
