1  AAIJ 2020R uses the ${{\mathit B}_{{{c}}}^{+}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \pi}^{+}}$, ${{\mathit J / \psi}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}{{\mathit \pi}^{+}}$, ${{\mathit J / \psi}}{{\mathit p}}{{\overline{\mathit p}}}{{\mathit \pi}^{+}}$, ${{\mathit J / \psi}}{{\mathit D}_{{{s}}}^{+}}$, ${{\mathit J / \psi}}{{\mathit D}^{0}}{{\mathit K}^{+}}$ and ${{\mathit B}_{{{s}}}^{0}}{{\mathit \pi}^{+}}$ modes.
2  Measured using ${{\mathit B}_{{{c}}}^{+}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit D}^{0}}{{\mathit K}^{+}}$ decays.
3  Uses ${{\mathit B}_{{{c}}}^{+}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit p}}{{\overline{\mathit p}}}{{\mathit \pi}^{+}}$ decays.
4  AAIJ 2013AS uses the ${{\mathit B}_{{{c}}}^{+}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit D}_{{{s}}}^{+}}$.
5  AAIJ 2012AV uses the ${{\mathit B}_{{{c}}}^{+}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \pi}^{+}}$ mode and also measures the mass difference M(${{\mathit B}_{{{c}}}^{+}}$) $−$ M(${{\mathit B}^{+}}$) = $994.6$ $\pm1.3$ $\pm0.6$ MeV/c${}^{2}$.
6  Measured using a fully reconstructed decay mode of ${{\mathit B}_{{{c}}}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \pi}}$.
7  ABE 1998M observed $20.4$ ${}^{+6.2}_{-5.5}$ events in the ${{\mathit B}_{{{c}}}^{+}}$ $\rightarrow$ ${{\mathit J / \psi}{(1s)}}{{\mathit \ell}}{{\mathit \nu}_{{{{{\mathit \ell}}}}}}$ with a significance of $>4.8$ standard deviations. The mass value is estimated from $\mathit m({{\mathit J / \psi}{(1S)}}{{\mathit \ell}}$).
8  ACKERSTAFF 1998O observed 2 candidate events in the ${{\mathit B}_{{{c}}}^{+}}$ $\rightarrow$ ${{\mathit J / \psi}{(1S)}}{{\mathit \pi}^{+}}$ channel with an estimated background of $0.63$ $\pm0.20$ events.
