      abstract     = {A precision measurement of the $ {B}_c^{+} $ meson mass is
                      performed using proton- proton collision data collected with
                      the LHCb experiment at centre-of-mass energies of 7, 8 and
                      13 TeV, corresponding to a total integrated luminosity of
                      9.0 fb$^{−1}$. The $ {B}_c^{+} $ mesons are reconstructed
                      via the decays $ {B}_c^{+} $→ J/ψπ$^{+}$, $ {B}_c^{+}
                      $→ J/ψπ$^{+}$π$^{−}$π$^{+}$, $ {B}_c^{+}\to J/\psi
                      p\overline{p}{\pi}^{+} $, $ {B}_c^{+}\to J/\psi {D}_s^{+} $,
                      $ {B}_c^{+} $→ J/ψ D$^{0}$K$^{+}$ and $ {B}_c^{+}\to
                      {B}_s^0{\pi}^{+} $. Combining the results of the individual
                      decay channels, the $ {B}_c^{+} $ mass is measured to be
                      6274.47 ± 0.27 (stat) ± 0.17 (syst) MeV/c$^{2}$. This is
                      the most precise measurement of the $ {B}_c^{+} $ mass to
                      date. The difference between the $ {B}_c^{+} $ and $ {B}_s^0
                      $ meson masses is measured to be 907.75 ± 0.37 (stat) ±
                      0.27 (syst) MeV/c$^2.$},
