A Monte Carlo Study on the Identification of Quark and Gluon Jets

High Energy Physics - Phenomenology 2007-05-23 v3

Abstract

Three jets events in the e+^+e^- collisions at 91.2 GeV are investigated using both HERWIG and JETSET Monte Carlo generators. The angles between the three jets are used to identify the quark and gluon jets. The analysis at parton level is done to ensure the reasonableness of this method and an angular cut is ultilized to improve the purity of this identification. The multiplicity inside the identified quark or gluon jets agree with the QCD predictions.
