title = "Precision measurement of the Bc+ meson mass",
abstract = "A precision measurement of the Bc+ 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 Bc+ mesons are reconstructed via the decays Bc+→ J/ψπ+, Bc+→ J/ψπ+π−π+, Bc+→J/ψpp¯π+, Bc+→J/ψDs+, Bc+→ J/ψ D0K+ and Bc+→Bs0π+. Combining the results of the individual decay channels, the Bc+ mass is measured to be 6274.47 ± 0.27 (stat) ± 0.17 (syst) MeV/c2. This is the most precise measurement of the Bc+ mass to date. The difference between the Bc+ and Bs0 meson masses is measured to be 907.75 ± 0.37 (stat) ± 0.27 (syst) MeV/c. [Figure not available: see fulltext.]",
