Revisiting $B_c^{-}\to J/\ddot{I}ˆ(\hat{I}{\cdot }_c)L^{-}$ decays within the SM and beyond in QCD factorization

Wei-Jun Deng, Fang-Min Cai, Xin-Qiang Li +2

Motivated by the deviations observed between the data and the SM predictions of $\mathcal{B}({\bar{B}}_s^0\to D_s^{+}\ddot{I}{€}^{-})$ and $\mathcal{B}({\bar{B}}_d^0\to D^{+}{K}^{-})$, we revisit the $…
