Abstract: (Elsevier)
It is shown that in Yang-Mills theory the vanishing of the radiative corrections to the matrix element of the topological charge is a manifestation of the index theorem for the operator, which enters the bilinear part of the Yang-Mills action in the background field gauge.- gauge field theory: Yang-Mills
- charge: topological
- perturbation theory: higher-order
