Precision Measurement of the Mass and Lifetime of the Ξ0b Baryon

Using a proton-proton collision data sample corresponding to an integrated luminosity of 3  fb−1 collected by LHCb at center-of-mass energies of 7 and 8 TeV, about 3800 Ξ0b→Ξ+cπ−, Ξ+c→pK−π+ signal decays are reconstructed. From this sample, the first measurement of the Ξ0b baryon lifetime is made, r...
