Hadrons rest mass comes from gluon field?

Click For Summary
The discussion centers on the relationship between gluons, quarks, and the mass of hadrons, highlighting that most of the rest mass in hadrons comes from the energy of the gluon field rather than the Higgs mechanism. While quarks gain mass from the Higgs field, the majority of hadron mass arises from the strong force and the interactions between quarks and gluons. The Higgs field imparts mass to fundamental particles, but its contribution to hadron mass is minimal compared to the binding energy from gluons. The conversation also touches on theories regarding the internal structure of particles and how mass might be derived from massless interactions. Ultimately, the Higgs remains essential for electroweak symmetry breaking, even if most mass originates from other sources.

Actually it has to do with charge conservation, nothing to do with SU(2) symmetry. Majorana mass terms violate U(1) symmetries if the corresponding fermion couples to that U(1) field

Yes, that's right. that's why most fermions cannot have a majorana mass. The right handed neutrino though is a U(1)xSU(2) singlet so it doesn't couple to any of the electroweak bosons.
