Type I Seesaw Mechanism, Lepton Flavour Violation and Higgs Decays (1303.5856v1)
Published 23 Mar 2013 in hep-ph
Abstract: We review and update the current phenomenological constraints on minimal type I seesaw extensions of the Standard Model in which New Physics content can be probed at the electroweak scale. In this class of models, the flavour structure of the neutrino Yukawa couplings is determined by the requirement of reproducing neutrino oscillation data. The strongest constraints on the seesaw parameter space are imposed by the very recent upper limit on \mu\ --> e \gamma\ decay rate. Searches of non-standard Higgs boson decays into a light and a heavy neutrino may also provide and independent test of these seesaw scenarios.
