Phys. Rev. D 79, 107703 (2009) [4 pages]Concerning gauge field fluctuations around classical configurationsReceived 5 April 2009; published 26 May 2009 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. © 2009 The American Physical Society URL:
