Radiative seesaw corrections and charged-lepton decays in a model with soft flavour violation
| Resumo: | We consider the one-loop radiative corrections to the light-neutrino mass matrix and their consequences for the predicted branching ratios of the five lepton-flavour-violating decays l1--> l2-l3+l3- in a two-Higgs-doublet model furnished with the type-I seesaw mechanism and soft lepton-flavour violation. We find that the radiative corrections are very significant; they may alter the predicted branching ratios by several orders of magnitude and, in particular, they may help explain why BR (mu (-) -> e(-)e(+)e(-)) is strongly suppressed relative to the branching ratios of the decays of the tau (-). We conclude that, in any serious numerical assessment of the predictions of this model, it is absolutely necessary to take into account the one-loop radiative corrections to the light-neutrino mass matrix. |
