Web10 Dec 2024 · Further the BRST invariance was used as a proper way of gauge fixing in skew-symmetric tensor gauge theories in which ghosts for ghosts necessarily appear in sequence [7], [8]. In these examples, the original FP path integral method does not work, or is very difficult to apply if not impossible. The procedure was neatly summarized in [9]. Yang–Mills theories are special examples of gauge theories with a non-abelian symmetry group given by the Lagrangian with the generators of the Lie algebra, indexed by a, corresponding to the F-quantities (the curvature or field-strength form) satisfying Here, the f are structure constants of the Lie algebra (totally antisymmetric if th…
