© 2016, The Author(s). We study several aspects of supersymmetric models with a U(1)R symmetry where the Higgs doublet is identified with the superpartner of a lepton. We derive new, stronger bounds on the gaugino masses based on current measurements, and also propose ways to probe the model up to scales of O(10 TeV) at future e+e− colliders. Since the U(1)R symmetry cannot be exact, we analyze the effects of R-symmetry breaking on neutrino masses and proton decay. In particular, we find that getting the neutrino mixing angles to agree with experiments in a minimal model requires a UV cutoff for the theory at around 10 TeV.
