Hi, I would like to understand what is the MΔ which appears in the neutrino mass mechanism with Type-II seesaw. It seems to be the Higgs triplet mass. But I do not understand what is (physically) the masse of this triplet when we define it with 3 components : Δ=(Δ++,Δ+,Δ°). It is different from...

My question concerns the chirality vs helicity for massive neutrinos. I know that as the mass is really light we can usually approximate helicity = chirality. But I would like to consider the exact case with the mass : i.e left handed (chirality )neutrino propagates with both left and right...
