Abstract

The Bc± meson is observed through the decay Bc±J/ψπ±, in data corresponding to an integrated luminosity of 2.4fb1 recorded by the Collider Detector at Fermilab II detector at the Fermilab Tevatron. A signal of 108±15 candidates is observed, with a significance that exceeds 8σ. The mass of the Bc± meson is measured to be 6275.6±2.9(stat)±2.5(syst)MeV/c2.
