Evidence for the exclusive decay Bc±→J/ψπ± and measurement of the mass of the Bc± meson

Evidence for the exclusive decay Bc±→J/ψπ± and measurement of the mass of the Bc± meson

We report the first evidence for a fully reconstructed decay mode of the Bc± meson in the channel Bc±→J/ψπ±, with J/ψ→μ+μ-. The analysis is based on an integrated luminosity of 360pb-1 in pp̄ collisions at 1.96 TeV center of mass energy collected by the Collider Detector at Fermilab. We observe 14.6...
