Quark and gluon jet properties at LEP
Abstract
Description
The study of the differences of the fragmentation of quarks and gluons to jets of hadrons gives insight into the fundamental structure of QCD. Results from different approaches to properties of quarks and gluons are shown. The colour factor ratio $C_A/C_F$ is measured in agreement with the QCD prediction. Identified particles in quark and gluon jets are investigated, revealing no overproduction of isoscalar $η^0$ and $ϕ(1020)$ in gluon jets, but an excess of protons.
