e^+e^-湮灭成两喷注中的末态强子快度分布和B■关联

RAPIDITY DISTRIBUTION AND BARYON-ANTIBARYON CORRELATIONS IN e^+e^--TWO JET-EVENTS

本文在文献[1]给出的模型中,进一步赋给夸克简单的四动量分布,通过Monte-Carlo计算,不但得到了与实验符合得很好的轻夸克喷注事例末态强子快度分布等,还给出了与实验基本一致的末态重子反重子之间的快度和角度关联.

We extend our model by introducing explicitly the energy-momentum of quarks. By using the Monte-Carlo method, the rapidity distribution in light jet events is calculated. Agreement with experiment data is good. The baryon-antibaryon correlations in rapidity, open angle, azimuthal angle are also given, which are in agreement with experiment on the whole.
