Tests of QCD using differences between gluon and quark jets
Abstract
I present recent results from LEP which utilize differences between gluon and quark jets to make quantitative tests of QCD. The principal topic is a determination of the ratio of QCD color factors, CA/CF, using either the multiplicity or fragmentation functions of the jets. In addition, I discuss a recent measurement of the rate of η mesons in gluon jets compared to quark jets.
