Non-abelian gauge theories as a consequence of perturbative quantum gauge invariance

چکیده
We show for the case of interacting massless vector bosons, how the structure of YangMills theories emerges automatically from a more fundamental concept, namely perturbative quantum gauge invariance. It turns out that the coupling in a non-abelian gauge theory is necessarily of Yang-Mills type plus divergenceand coboundary couplings. The extension of the method to massive gauge theories is briefly discussed.

متن کاملThe renormalizability for massive Abelian gauge field theories re-visited
We give a simplified proof for the perturbative renormalizability of theories with massive vector particles. For renormalizability it is sufficient that the vector particle is treated as an gauge field, corresponding to an Abelian gauge group. Contrary to the non-Abelian case one does not need the Higgs mechanism to create the appropriate mass terms. The proof uses “Stueckelberg’s trick” and th...
متن کاملOn gauge invariance and spontaneous symmetry breaking
We show how the widely used concept of spontaneous symmetry breaking can be explained in causal perturbation theory by introducing a perturbative version of quantum gauge invariance. Perturbative gauge invariance, formulated exclusively by means of asymptotic fields, is discussed for the simple example of Abelian U(1) gauge theory (Abelian Higgs model). Our findings are relevant for the electro...
متن کاملFlow Equations for Yang-Mills Theories in General Axial Gauges
We present a formulation of non-Abelian gauge theories in general axial gauges using a Wilsonian (or ’Exact’) Renormalisation Group. No ’spurious’ propagator divergencies are encountered in contrast to standard perturbation theory. Modified Ward identities, compatible with the flow equation, ensure gauge invariance of physical Green functions. The axial gauge nA = 0 is shown to be a fixed point...
متن کاملAbelian chiral gauge theories on the lattice with exact gauge invariance
It is shown that U(1) chiral gauge theories with anomaly-free multiplets of Weyl fermions can be put on the lattice without breaking the gauge invariance or violating any other fundamental principle. The Ginsparg-Wilson relation plays a key rôle in this construction, which is non-perturbative and includes all topological sectors of the theory in finite volume. In particular, the cancellation of...
