Higgs, neutrinos, and standard model status

bsaucer · Mar 30, 2013

I've always understood that the "formula" for the Standard Model is SU(3) × SU(2) × U(1). Since the discovery of the Higgs boson, and observations of neutrino flavor oscillations, has that formula been revised, or is it still the same?

With the Higgs mechanism, is SU(3) × [SU(2) × U(1) broken to U(1)]. And it describes the interactions (bosons) only, not the leptons.
Neutrinos are leptons, they don't care about those symmetries in their mixing.
