Average Multiplicities in Gluon and Quark Jets in Higher-Order Perturbative QCD
I. M. Dremin, V. A. Nechitailo
Abstract
The ratio of average multiplicities in gluon and quark jets is shown to become noticeably smaller in higher-order QCD compared to its lowest order value what improves agreement with experiment. QCD anomalous dimension has been calculated. It has been used to get energy dependence of mean multiplicities.
