Abstract
© 2017 The Author(s) The observation of the decay Ξb−→J/ψΛK−is reported, using a data sample corresponding to an integrated luminosity of 3fb−1, collected by the LHCb detector in pp collisions at centre-of-mass energies of 7 and 8TeV. The production rate of Ξb−baryons detected in the decay Ξb−→J/ψΛK−is measured relative to that of Λb0baryons using the decay Λb0→J/ψΛ. Integrated over the b-baryon transverse momentum pT<25GeV/c and rapidity 2.0
