$\mu \to e\gamma$ and $\tau \to l\gamma$ decays in the fermion triplet seesaw model

A. Abada, C. Biggio, F. Bonnet +2

In the framework of the seesaw models with triplets of fermions, we evaluate the decay rates of $\mu \to e\gamma$ and $\tau \to l\gamma$ transitions. We show that although, due to neutrino mass c…
