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