1  The ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit D}_{{{s}}}^{*-}}{{\mathit \mu}^{+}}{{\mathit \nu}_{{{\mu}}}}$ decay is reconstructed through the decays of ${{\mathit D}_{{{s}}}^{*-}}$ $\rightarrow$ ${{\mathit D}_{{{s}}}^{-}}{{\mathit \gamma}}$, ${{\mathit D}_{{{s}}}^{-}}$ $\rightarrow$ ${{\mathit K}^{-}}{{\mathit K}^{+}}{{\mathit \pi}^{-}}$.
2  The ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit D}_{{{s}}}^{*-}}{{\mathit \mu}^{+}}{{\mathit \nu}_{{{\mu}}}}$ decay is reconstructed inclusively without ${{\mathit \gamma}}$ from the decays of ${{\mathit D}_{{{s}}}^{*-}}$ $\rightarrow$ ${{\mathit D}_{{{s}}}^{-}}{{\mathit \gamma}}$, ${{\mathit D}_{{{s}}}^{-}}$ $\rightarrow$ ${{\mathit K}^{-}}{{\mathit K}^{+}}{{\mathit \pi}^{-}}$.
