A Understanding the Mass of the Higgs Triplet in Neutrino Mass Mechanism

[chym]

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 the Δ° mass ?
Thanks

Unless you provide us with a reference where your notation is introduced, how do you expect anyone to answer this question?

You are right. But my question can be reformulated.
In some theories (see saw II or III), we assume the existence of a scalar SU(2)L triplet defined by Δ=(Δ++,Δ+,Δ°) (=Higgs triplet) or new fermionic SU(2) triplet Σ=(Σ+,Σ°,Σ-). In such models, we refer on the mass of the triplet mΔ or mΣ. My question is that I do not understand how we can speak about the triplet mass (and not about each of its component mass). For comparison, in SU(2)L doublet ψ=(ν,e-) we always refer either on the neutrino mass or electron mass and not on a "mψ" doublet mass. So this triplet mass term (mΣ or mΔ) is difficult for me to understand. Could you help me ?
