Book Description
The energy dependence of the relative production rate of 3-jet events is studied in hadronic ee− annihilation events at centre of mass energies between 22 and 56 GeV, using the data of the JADE, MARK-II and AMY collaborations at PETRA, PEP and TRISTAN. Three jet events are defined by a jet finding algorithm which is closely related to the definition of resolvable jets used in O(.cap alpha./sub s/2) perturbative QCD calculations, where the relative production rate of 3-jet events is roughly proportional to the strong coupling strength, .cap alpha./sub s/. The observed production rates of 3-jet events decreases significantly with increasing centre of mass energy. The results, which are independent of fragmentation model calculations, can be directly compared to theoretically calculated jet production rates and are in good agreement with the QCD expectations of a running coupling strength, while the hypothesis of an energy independent coupling constant can be excluded with a significance of 5 standard deviations. Based on these results, the presented jet analysis also provides the possibility to detect first signs of the production of new and heavy particles in the early stage of data taking at SLC and LEP.

Author:

Languages : en
Pages :
Book Description
The latest results on R, the ratio of the total cross section for production of multihadronic events to the muon pair production cross section, and inclusive distributions of hadrons from ee− annihilation in the center-of-mass energy range from 2.6 to 7.8 GeV are presented. The evidence for jet structure is reviewed. Inclusive distributions of hadrons in Feynman x, rapidity, and transverse momentum relative to the jet direction are studied. Particular emphasis is placed on the method used to measure these inclusive distributions and the biases which might result from this method.
