Observation of the decay Bc±→J/ψπ± and measurement of the Bc± mass

Observation of the decay Bc±→J/ψπ± and measurement of the Bc± mass

The Bc± meson is observed through the decay Bc±→J/ ψπ±, in data corresponding to an integrated luminosity of 2.4fb-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 Bc±...
