Abstract: (APS)

A measurement of the ratio of branching fractions of the decays B+→K+μ+μ- and B+→K+e+e- is presented. The proton-proton collision data used correspond to an integrated luminosity of 5.0 fb-1 recorded with the LHCb experiment at center-of-mass energies of 7, 8, and 13 TeV. For the dilepton mass-squared range 1.1

Note:
