Large p_T Jets and Correlating Quark Rearrangement Model

概要

論文の詳細を見る
Large p_t jet productions are studied from the viewpoint of correlating quark rearrangement model in which the correlations among quarks and the color singlet constraints of quark rearrangement play essential roles. Four-jet structure in large p_t events is derived. The factors ascribed to the spectator, to the hard-rearrangement and to the extraction mechanism are defined and their forms are determined concretely. Though these factors correspond to the distribution function in the parton model, respectively, their meanings are quite different from each other. The spectator factor, which shows scaling behavior, represents the degree of difficulty of quarks in making large momentum transfer but does not mean the distribution function of momentum fraction of quarks. The hard-rearrangement factor is considerably affected by the correlations among quarks. The extraciton factor is also influenced by the constraints to compose the final state of color singlet hadrons and shows a significantly non-scaling feature.
