Abstract

We report the calculation of the fourth coefficient in an expansion of the heat kernel of a non-minimal, non-Abelian kinetic operator in an arbitrary background gauge in arbitrary spacetime dimension. The fourth coefficient is shown to bring a non-trivial gauge dependence due to the contribution of the lowest order off-shell gauge-invariant structure.
