Observation of the B(c) meson in the exclusive decay B(c)-> J/psi pi

A fully reconstructed B(c)-> J/psi pi signal is observed with the D0 detector at the Fermilab Tevatron p (p) over bar collider using 1.3 fb(-1) of integrated luminosity. The signal consists of 54 +/- 12 candidates with a significance that exceeds 5 standard deviations, and confirms earlier ob...

Zusammenfassung:A fully reconstructed B(c)-> J/psi pi signal is observed with the D0 detector at the Fermilab Tevatron p (p) over bar collider using 1.3 fb(-1) of integrated luminosity. The signal consists of 54 +/- 12 candidates with a significance that exceeds 5 standard deviations, and confirms earlier observations of this decay. The measured mass of the B(c) meson is 6300 +/- 14(stat)+/- 5(syst) MeV/c(2).
