Quark-Gluon Jet Differences at LEP
Jon Pumplin
Abstract
A new method to identify the gluon jet in 3-jet `` Y'' decays of Z0 is presented. The method is based on differences in particle multiplicity between quark jets and gluon jets, and is more effective than tagging by leptonic decay. An experimental test of the method and its application to a study of the ``string effect'' are proposed. Various jet-finding schemes for 3-jet events are compared.
