Ds+πK衰变过程的软胶子效应研究

Soft-Gluon Exchange Effect in Ds+πK Decays

  • 摘要: 本文在QCD因子化方法的基础上利用光锥QCD求和规则研究了Ds+πK两个衰变道中的软胶子交换效应,并在衰变总振幅中加入了来自软胶子交换的贡献。计算结果与实验数据符合得很好。

     

    Abstract: In this paper, based on the QCD factorization (QCDF), the soft-gluon exchange effect in Ds+πK0 and Ds+π0K+ decays was studied by using light-cone QCD sum rules. After taking the contribution from the correction of soft-gluon effect into account in the total decay amplitude, it is found that the final results of calculation are consistent with the latest experiment data.
