| Descripción: | Gauge theories and their BRST invariance are reviewed. Gauge-invariant (color) subamplitudes for non-Abelian gauge theories are discussed. BRST transformations of non-Abelian vertices are derived, and are used to obtain the gauge transformation of any Feynman diagram. From this minimal set of gauge-invariant subamplitudes in perturbation theory can be found. This knowledge is useful in the application of the spinor helicity technique, and is indispensible for future developments of non-Abelian perturbation theories. |
