摘要
本文对e^-e^-湮没过程中的两类不同碎裂机制做了比较.进一步计算出末态强子多重数与实验结果比较,发现“独立碎裂“假定与实验矛盾,而“弦碎裂“假定符合较好.
The comparison of two fragmentation schemes used in the analysis of e^+e^- annihilation are presented in this paper. It is found that the independent fragmentation assumption is strongly disfavored by the data of the final particle multiplicities, and the string fragmentation assumption agrees with experiments.
