N. Ghahramany, A. R. Houshyar

AI总结:

本文利用三点QCD求和规则并考虑双胶子凝聚贡献,计算了χ_{c1}(1p)→D_{s}^{+}e\ar{ν}稀有半轻衰变的跃迁形状因子、总衰变宽度和分支比。

摘要:

利用三点QCD求和规则分析了稀有的半轻衰变χ_{c1}(1p)→D_{s}^{+}e\ar{ν}。考虑双胶子凝聚贡献后,计算了与该衰变相关的跃迁形状因子,并利用它们确定了总衰变宽度和分支比。我们的结果可能会被未来的实验所证实。

英文摘要:

The rare semileptonic $χ_{c1}(1p)\rightarrow D_{s}^{+}e\bar{ν}$ decay is analyzed, by using the three-point QCD sum rules. Taking into account the two-gluon condensate contributions, the transition form factors related to this decay are calculated and are used to determine the total decay width and branching fraction. Our findings may be approved by future experiments.
