Test of lepton universality with Λ b 0 → pK − ℓ + ℓ − decays

The ratio of branching fractions of the decays Λb0 → pK−e+e− and Λb0 → pK−μ+μ−, RpK−1, is measured for the first time using proton-proton collision data corresponding to an integrated luminosity of 4.7 fb−1 recorded with the LHCb experiment at center-of-mass energies of 7, 8 and 13 TeV. In the dilep...
