hello sorry for not posting that long. yes, indeed this wikipedia article is a little short and cannot help me with my problem. neither could the textbooks that i tried: peskin & schroeder (introduction to quantum field theory), ryder (qft) and bjorken drell (relativistic quantum field...

hi sam! thank you for your answer! it was a great help for me. i remember my professor saying that the gauge fields transform in the adjoint representation. up to now it's not yet clear to me, how the gauge transformation "prescription" A_{\mu}'=UA_\mu U^{-1}+\frac{i}{g} U (\partial _\mu...
