Abstract
The Ξb0→Ξc+Ds−andΞb−→Ξc0Ds− decays are observed for the first time using proton-proton collision data collected by the LHCb experiment at a centre-of-mass energy of sqrt{s}=13TeV, corresponding to an integrated luminosity of 5.1fb-1. The branching fractions times the production cross-sections of Xib baryons relative to that of \Lambdab0 baryon are measured to be (Formula presented.) where the first uncertainties are statistical, the second systematic, and the third due to the uncertainties on the decay branching fractions of relevant charmed baryons.File in questo prodotto:
