WH->WWW(*)->lnulnu+X. The data were collected with the CDF and D0 detectors
at the Tevatron collider at Fermilab, and correspond to an integrated

We update the constraints from electroweak precision data on new leptons and scalars that can give Majorana masses to light neutrinos. The allowed mixings and couplings are large enough to make these particles observable at LHC, as long as an extra symmetry suppresses their contributions to light neutrino masses.

The \mu -> e \gamma and \tau -> l \gamma decay rates are evaluated in the framework of the seesaw model with triplets of fermions.
