Scale Breaking in Quark and Gluon Jets in Electron Positron Annihilations, using AMY Data

We have studied hadronic events for e+e− annihilation by using real AMY data as well as Monte Carlo simulated events. We present mean cone angle and transverse momentum for quark and gluon jets. We observe that the cone angle for gluon jet sample is wider than that for quark jet. Transverse momentum with respect to the jet axis is also higher for gluon jet. Next we study scaling violation for two kinds of jets. Due to the higher color factor for gluon jet, it shows a stronger scaling violation compared to quark jet. A good agreement is found between measurements and corresponding QCD predictions. We will explain all these features in this paper.
