A Monte Carlo study on the production scale and internal structure of jets in high energy collisions

导出

摘要 The production scale and internal structure of jets produced in high energy collisions were studied using Jetset and Herwig Monte Carlo generators. Two scales were found. One is the jet-development scale, which determines the size of the jet developed from a mother-parton. The other is the jet-production scale with which the jets produced are the most consistent with QCD jet-production dynamics and will provide the most reliable dynamical information about their mother-partons.
