luminosity of 3 fb-1 collected by LHCb at center-of-mass energies of 7 and 8 TeV, about 3800 Ξ0b Ξ+ cπ-, Ξc+ pK-π+ signal decays are reconstructed. From this sample, the first measurement of the Ξ0 b baryon lifetime is made, relative to that of the Λ0 b baryon. The mass differences M(Ξ0 b) - M(Λ0 b) and M(Ξc+) - M(Λc+) are also measured with precision more than 4 times better than the current world averages. The resulting values are (Equation presented) where the first factor is the ratio of fragmentation fractions, b Ξ0 b relative to b Λ0 b. Relative production rates as functions of transverse momentum and pseudorapidity are also presented. © 2014 CERN, for the LHCb Collaboration.EnglishAll Open Access; Hybrid Gold Open AccessAtomic physicsPhysicsCenter-of-mass energiesIntegrated luminosityMass differencePrecision measurementProduction ratesProton proton collisionsPseudorapiditiesTransverse momentaHadronsArticle10.1103/PhysRevLett.113.032001
