The B-c(+) mesons are reconstructed via the decays B-c(+)-> J/psi pi(+), B-c(+)-> J/psi pi(+)pi(-)pi(+), B-c(+)-> J/psi pppi(+), B-c(+)-> J/psi D-s(+), B-c(+)-> J/psi (DK+)-K-0 and B-c(+)-> 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).", optnote="WOS:000553446200002", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=4482), last updated on Tue, 11 Aug 2020 08:20:34 +0000", issn="1029-8479", doi="10.1007/JHEP07(2020)123", opturl="https://arxiv.org/abs/2004.08163", opturl="https://doi.org/10.1007/JHEP07(2020)123", language="English" }
