Nonfactorizable soft contributions in the $B⟶{\eta }_{c}K,{\chi }_{c0}K$ decays with the light-cone sum rules approach

Zhi-Gang Wang, Lin Li, Tao Huang

In this article, we calculate the nonfactorizable soft contributions in the $B\to {\eta }_{c}K,{\chi }_{c0}K$ decays with the light cone QCD sum rules approach. Our results show that the non…
