Description

LFV processes have been studied extensively in this model (JHEP 07 (2019) 154). We study systematically the phenomenological consequences of introducing inverse see-saw neutrino masses in the model (according to JHEP 12 (2019) 154) and obtain predictions on the $\tau \to \ell \gamma$ and $\tau \to \ell {\ell }^{\prime }{\ell }^{\prime }$ decays (other LFV decays are also analyzed) which are close to current experimental bounds. Besides, the introduction of these TeV Majorana neutrinos allows for wrong-sign $\tau \to \ell \ell {\ell }^{\prime }$ decays, at a rate which can also be probed by Belle-II.
