在模型III下计算了对B介子稀有衰变过程的新物理贡献.在所考虑的参数空间里,发现:对稀有衰变的新物理贡献能够使其分支比提高一到两个数量级,接近目前的实验测量限制;根据ALEPH等实验组的实验测量数据,可以给出对Yukawa耦合tλt的限制.
A new physical contribution to the rare decay process of B mesons has been calculated under Model III. In the parameter space considered, it was found that a new physical contribution to rare decay can increase its branching ratio one to two orders of magnitude closer to the current experiment Measurement Limits; Based on the experimental measurements of experimental groups such as ALEPH, the restriction on the Yukawa coupling tλt can be given.
