摘要

We describe recent applications of the MLLA evolution equations to the calculation of mean multiplicities in quark and gluon jets and the higher moments of hadron and sub-jet multiplicity distributions in $e^+e^-$ -annihilation as function of c.m.s. energy $Q$ and resolution parameter $y_{cut}$ . The transition from jets to hadrons with increasing jet resolution is considered.
