Study on the Cabibbo-favored ${\overline{B}}_{d,s}$ $\to$ $D_{d,s}^{(\ast )+}{S}^{-}$ weak decays in QCD factorization

Lili Chen, Chenyang Jing, Kaiyuan Gao +2

Motivated by recent experimental progress and theoretical developments, we investigate the Cabibbo-favored $b\to c$ governed ${\overline{B}}_{d,s}$ $\to$ $D_{d,s}^{(\ast )+}{S}^{-}$~($S…
