Researchers have re-evaluated a specific class of scotogenic models, known as "T1-2-A", which aim to simultaneously explain neutrino oscillation data and propose a viable dark matter candidate. The study focused on charged lepton flavor violating (cLFV) decays, particularly in rare muon transitions. The results suggest that these models can predict significant rates for cLFV observables, opening new avenues for experimental detection.

The work explores in detail the model's parameter space, identifying regions where cLFV rates are appreciable. Furthermore, the scientists have considered the role of parity and time-reversal asymmetries in three-body lepton decays, specifically in processes like $\ell_\alpha^+ \to \ell_\beta^+ \ell_\gamma^+ \ell_\delta^-$. These asymmetries could be experimentally investigated in association with polarized muon and tau decays.

The inclusion of these new observables offers complementary information on the "T1-2-A" scotogenic model, providing additional means to test its validity. If these asymmetries or the predicted cLFV rates were detected, it would strengthen the hypothesis that these models can describe phenomena beyond the Standard Model, such as the nature of dark matter and the origin of neutrino masses.
