Characteristics of Photon-Photon Initiated 3 Jet Events in QCD

摘要

The properties of photon-photon initiated 3-jet events of the type e exp + e exp - implies e exp + e exp - qg(q anti q) + beam pipe jet are discussed. Expressions are derived in QCD for the total energy, longitudinal momentum and transverse momentum distributions of the beam pipe jet. These results are based on a generalization of Witten's result on photon structure functions to a distribution of two partons in a photon. The derivation is a novel application of jet calculus. The charge correlations typical of the 3 jet events are also analysed. (Atomindex citation 11:526716)
