Abstract |
The Ξ0b→Ξ+cD−s and Ξ−b→Ξ0cD−s decays are observed for the first time using proton-proton collision data collected by the LHCb experiment at a centre-of-mass energy of s√=13TeV, corresponding to an integrated luminosity of 5.1fb−1. The relative branching fractions times the beauty-baryon production cross-sections are measured to be (formula), where the first uncertainties are statistical, the second systematic, and the third due to the uncertainties on the branching fractions of relevant charm-baryon decays. The masses of Ξ0b and Ξ−b baryons are measured to be mΞ0b=5791.12±0.60±0.45±0.24MeV/c2 and mΞ−b=5797.02±0.63±0.49±0.29MeV/c2, where the uncertainties are statistical, systematic, and those due to charm-hadron masses, respectively. |
