1  Uses exclusively reconstructed final states ${{\mathit \Lambda}_{{{b}}}^{0}}$ $\rightarrow$ ${{\mathit \Lambda}_{{{c}}}^{+}}{{\mathit D}_{{{s}}}^{-}}$ , ${{\mathit \Lambda}_{{{c}}}^{+}}{{\mathit D}^{-}}$ and ${{\overline{\mathit B}}^{0}}$ $\rightarrow$ ${{\mathit D}^{+}}{{\mathit D}_{{{s}}}^{-}}$ decays.
2  Uses exclusively reconstructed final states containing ${{\mathit J / \psi}}$ $\rightarrow$ ${{\mathit \mu}^{+}}{{\mathit \mu}^{-}}$ decays.
