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.
