Measurement of the mass and lifetime of the Ωb- baryon

Abstract:

A proton-proton collision data sample, corresponding to an integrated luminosity of 3fb−1 collected by LHCb at √s = 7 and 8 TeV, is used to reconstruct 63 ± 9 Ωb- → Ω0cπ−, Ω0c → pK−K−π+ decays. Using the Ξ−b → Ξ0cπ−, Ξ0c → pK−K−π+ decay mode for calibration, the lifetime ratio and the absolute lifetime of the Ω−b baryon are measured to be τΩ−b/τΞ−b = 1.11 ± 0.16 ± 0.03, τΩb− = 1.78 ± 0.26 ± 0.05 ± 0.06 ps, where the uncertainties are statistical, systematic and from the calibration mode (for...
