Assumption: Renormalization class

The current has the fixed Noether normalization (eq:classicalcurrent). Renormalization is local and gauge covariant, state independent, compatible with the standard engineering dimension and charge conjugation, and normalized to zero in the ordinary Minkowski vacuum with trivial connection. Only the usual local background counterterms are allowed.

No preferred radial vector, angular Killing field, global Wilson loop, or apex-supported distribution is admitted as an additional local subtraction datum.
