Anyway, gauge invariance is broken by the mass term. The three point interaction term contains a derivative, which means that the feynman rule for the threepoint vertex involves the momenta of the particles going into the vertex.

This is invariant under the nonabelian gauge transformations 28. For nonabelian gauge theories the gauge bosons interact with each other via both threepoint and fourpoint interaction terms. Nonabelian group, in mathematics, a group that is not abelian commutative nonabelian gauge theory, in physics, a gauge group that is nonabelian. For instance, phase transformations constitute the group u 1, which is clearly. Pdf octonionic nonabelian gauge theory b c chanyal.
