Measurement of the Lambda(0)(b), Xi(-)(b), and Omega(-)(b) Baryon Masses

Measurement of the Lambda(0)(b), Xi(-)(b), and Omega(-)(b) Baryon Masses

Bottom baryons decaying to a J/ψ meson and a hyperon are reconstructed using 1.0 fb-1 of data collected in 2011 with the LHCb detector. Significant Λb0→J/ψΛ, Ξb-→J/ψΞ- and Ωb-→J/ψΩ- signals are observed and the corresponding masses are measured to be M(Λb0)=5619.53±0.13(stat.) ±0.45(syst.) MeV/c2, M...
