Test of lepton universality with Λb0→pK−ℓ+ℓ−$$ {\Lambda}_b^0\to {pK}^{-}{\mathrm{\ell}}^{+}{\mathrm{\ell}}^{-} $$ decays
Abstract The ratio of branching fractions of the decays Λb0$$ {\Lambda}_b^0 $$ → pK−e+e− and Λb0$$ {\Lambda}_b^0 $$ → pK−μ+μ−,RpK−1$$ {R}_{pK}^{-1} $$, 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 exper...
