e^+e^-湮没成两喷注中的半单举分布及多重数分布的快度依赖性

SEMI-INCLUSIVE DISTRIBUTIONS AND RAPIDITY DEPENDENCE OF MULTIPLICITY DISTRIBUTIONS IN e^+e^- ANNIHILATION INTO TWO JETS

本文假设夸克的快度分布是四动量守恒限制下的均匀分布,通过Mont-Carlo计算,得到了轻夸克喷注中末态强子的半单举分布以及不同快度区间内的多重数分布,讨论了它们的基本特征,并与现有的平均喷注实验数据作了比较.

In this paper, the rapidity distribution of quarks is further assumed to be a uniform distribution with the constraint of four momentum conservation. We apply Mbnte Carlo approaches to light quark jets. The semi-inclusive distributions and the multiplicity distributions in rapidity intervals are calculated. The characteristics of these distributions are discussed and the results are compared with the experimental data of average jets.
