8 µ − e conversion can be within the reach of projected experiments (see [25]). 25 We collect in Table II the percentage of points that satisfies all the experimental tests for different ranges of c$_{3}$ and v/ Λ. Requiring c$_{3}$ ≥ 0 . 55 and v/ Λ ≤ 0 . 05 we find that 91% of the points pass all current experimental constraints (53% if we include the projected MEG sensitivity on µ → eγ ). For v/ Λ small enough, all tree-level LFV effects are negligible, and the only (mild) constraint comes from µ → eγ . Note, however, that in our scans we have randomly selected order one values of the dimensionless couplings and fixed the global scale through the ratios v $^{(}$′) ( η $_{)}$/ Λ $^{(}$′$^{)}$. The unbalanced sensitivity of µ → eγ forces the global scale to be small, and then all other effects are almost negligible, including deviations from Let us discuss the scanning over the model parameters. Electroweak tests are generically satisfied for our choice of IR scale 1 /R ′ = 1 . 5 TeV, as expected for UV localized light fermions [15] (with partial protection of universality for Z couplings). The constraints from tree-level LFV are also typically mild, due to the double layer of flavor protection in our model. Among the processes considered only µ → eee and µ − e conversion are close to current experimental limits. In our general scan up to ∼ 70% and ∼ 51% of the points pass the corresponding bounds, respectively. 8 The main constraint turns out to arise from µ → eγ . In general the new contributions are smaller for smaller values of v/ Λ and relatively large values of c$_{3}$ . On the other hand, the departure from TBM mixing is somewhat sensitive to the value of v ′ / Λ ′ , decreasing with this ratio. Thus, in the following we fix v ′ / Λ ′ = 0 . 05 to ensure a nearly correct neutrino mixing, passing ∼ 82% of the points the PMNS test when varying the other parameters. These are randomly selected with 0 ≤ v$_{η}$/ Λ , v ′ $_{η}$/ Λ ′ ≤ 0 . 3 and c$_{3}$ ≥ 0 . 5. v/ Λ is computed from Eq. (45). In the Figure we show the most restricting observables as a function of this ratio, together with the corresponding current experimental limit (solid line). These are µ → eee (top-left panel), µ − e conversion in nuclei (top-right panel) and µ → eγ (lower panels, with the full range of v/ Λ on the left and only small v/ Λ values on the right), for which we have also drawn the expected sensitivity from MEG (dashed line). The extra flavor protection of tree-level mediated processes in the top panels relative to the one-loop µ → eγ decay can be clearly observed in the Figure. As we see, a large number of points passes the different tests for relatively small v/ Λ values. If we restrict ourselves to v/ Λ ≤ 0 . 05, about 97% of the points pass the µ → eee and µ − e conversion tests, whereas 61% satisfy the µ → eγ bound (and only 28% the expected MEG sensitivity).
