Phenomenological study of diquark effects in ${\bar{B}}_{(s)}^0\to D_{(s)}^{(\ast )+}{L}^{-}$ decays

Fang-Min Cai, Xin-Qiang Li, Tong-Kai Liu +2

Motivated by the deviations between experimental data and SM predictions for the branching fractions of ${\bar{B}}_{(s)}^0\to D_{(s)}^{(\ast )+}{L}^{-}$ decays with $L=\pi ,K^{(\ast )},\rho$, we in…
