Abstract The B±c meson is observed through the decay B±c→J/ψπ±, in data corresponding to an integrated luminosity of 2.4  fb−1 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 B±c meson is measured to be 6275.6±2.9(stat)±2.5(syst)  MeV/c2.
