摘要
本文假定e^+e^-湮没时产生的胶子的强子化,胶子首先劈裂成一对等效的夸克、反夸克对.夸克之间的色相互作用,碎裂成末态强子.由此计算的e^+e^-→3jet事例中的带电粒子多重数,胶子与夸克jet中多重数比率,以及e^-e^-三胶子事例中的重子比率,都与实验结果一致.解释了e^+e^-→3jet末态粒子的角分布.
In this paper, we suggest that the gluon is hadronized by first splitting into a quark-antiquark pair(?) The final hadrons are produced by the color interactions among the quarks and antiquarke. By this assumption, the calculated average charged particle multiplicities in e^+e^-→3 jet events, and the ratio of multiplicities between gluon and quark jet, and the rates of baryons in e^+e^- three gluons events all agree well with experiments. The angle distribution of final particles can be explained.
