Precision Measurement of the Mass and Lifetime of the Ξb− Baryon
R. Aaij, B. Adeva, M. Adinolfi, A. Affolder et autres
We report on measurements of the mass and lifetime of the ${\mathrm{\ensuremath{\Xi}}}_{b}^{\ensuremath{-}}$ baryon using about 1800 ${\mathrm{\ensuremath{\Xi}}}_{b}^{\ensuremath{-}}$ decays reconstructed in a proton-proton collision data set corresponding to an integrated luminosity of $3.0\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ collected by the LHCb experiment. The decays are …
