Nature of problem:
For the study of jets in high energy reactions, a Monte-Carlo event generator of QCD is indispensable. In order to determine the QCD fundamental parameter, i.e., the strong coupling constant, the parton- shower method including next-to-leading order terms is required.
Based on the formulation of QCD parton shower beyond the leading order, all terms up to the next-to-leading order are implemented into NLLjet. Detailed discussion on kinematics of parton shower is presented in this paper.
On FACOM-M780, NLLjet generates 120 events/s of parton shower for W= 91 GeV and Qo**2 = 1GeV**2. When it is linked with the LUND6.3 hadronization model with a set of typical parameters, 24 hadronic events are generated per second.
