### Abstract

The product of the Λ0b (B⎯⎯⎯⎯0) differential production cross-section and the branching fraction of the decay Λ0b→J/ψpK− (B⎯⎯⎯⎯0→J/ψK⎯⎯⎯⎯∗(892)0) is measured as a function of the beauty hadron transverse momentum, pT, and rapidity, y. The kinematic region of the measurements is pT<20 GeV/c and 2.0
