Abstract

We show that, unlike mass matrices, the fermionic gauge currents of the Standard Model exhibit, at the quantum level, remarkable SU(2)_f flavor properties at the observed values of the mixing angles. They accommodate all measured mixing for three families of quarks, and, for neutrinos, maximal theta₂₃, quark-lepton complementarity tan(2 theta_c)=1/2 <--> tan (2 theta₁₂)=2, and a not so small sin²(2 theta₁₃) = .267 within the present 90% c.l. interval of the T2K experiment.
