These lead to both extensive as well as non-extensive effective actions, which have very distinct behavior in the long wavelength and static limits. We discuss a large gauge Ward identity for the leading terms in the static limit, whose solution coincides with the effective action proposed earlier.9 pages, 2 figuresHigh Energy Physics - PhenomenologyHigh Energy Physics - Theorytext
