最近提出Ｗ~＋Ｗ~－强子衰变过程中的负关联效应可能是色重组的信号。采用随机级联 ａ模型研究这一效应。在模型中假设色重组导致 Ｗ~ ＋ Ｗ~－衰变形成的两个未态系统之间的粒子发生交换。根据这一物理图象可以再现Ｐｙｔｈｉａ事件产生器所得到的负关联。
Recently, it is proposed that the negative correlation effect during the decay of W ~ + W ~ - mayors is a signal of color recombination. This effect was studied using a random cascade model. In the model, it is assumed that the chromosomal recombination leads to the exchange of particles between two non-state systems formed by W ~ + W ~ - decay. Based on this physical image, the negative correlation obtained by the Pythia event generator can be reproduced.
