In our case Q = − 2 , − 1 , 0 (and +1 if heavier modes are included). The relevant couplings, ignoring e and µ , read and random order one dimensionless coefficients for higher order operators. The spectrum reproduces the observed pattern of charged lepton and neutrino masses and mixing angles. Above them, there is an almost degenerate bi-doublet, whose matter content we denote by N$_{L,R}$ , T 1 $_{L,R}$, T 2 L,R and Y$_{L,R}$ , all with masses ≈ 410 GeV. Other fermionic resonances have masses ≳ 3 TeV. 9 The bosonic resonances are all above 3 . 5 TeV. The lepton couplings to the SM bosons can be written 28
