Abstract
An extension of the Zee model involving a light right handed neutrino, nu_R is considered. We update constraints on couplings between the bilepton scalar, the active neutrinos, nu_R and the charged leptons. We find that the most stringent constraint currently comes from measurements limiting the width of the decay mu -> e gamma. These are used to predict the upper bound on violation of lepton universality in leptonic W boson decays and rare Z decays, such as Z -> e mu.
