Concerning gauge field fluctuations around classical configurations
arXiv:0904.0820 · doi:10.1103/PhysRevD.79.107703
Abstract
We treat the fluctuations of non-Abelian gauge fields around a classical configuration by means of a transformation from the Yang--Mills gauge field to a homogeneously transforming field variable. We use the formalism to compute the effective action induced by these fluctuations in a static background without Wu--Yang ambiguity.
