本文研究了e^+e^-湮灭反应中四夸克系统Q Q^-Q'Q^-'的一种特殊的色连接方式,讨论了相应的末态强子能量、动量分布等强子化效应,并发现这种没有色分离的特殊色连接方式有利于双重重子,如X、Y、Z粒子等新束缚态的产生,实验上可通过三喷注类事例来进行鉴别寻找.
We investigate a special color connection of four heavy quark system and the corresponding hadronization effects in e ^+ e ^- annihilation. This special color connection without color - separation favors the production of the doubly heavy baryons, and the three -jet events can be used to tag and search these doubly heavy baryons production.
