Field-strength formulation of gauge theories: Transformation of the functional integral

Journal Article · · Phys. Rev. D; (United States)
We present a formulation of gauge field theories in which the gauge potentials A/sub ..mu../(x) are eliminated in a simple way in terms of the field strengths F/sub munu/(x). Our results are closely related to, but are much simpler than, Halpern's dual variable formulation of gauge theories in the axial gauge. We work in the coordinate gauge x/sup ..mu../A/sub ..mu../(x) = 0, and show both analytically and geometrically that the potential A/sub ..mu../ can be determined uniquely from the field strengths F/sub munu/ for a suitable class of F's, A..-->..A(F). We show, furthermore, that a tensor F/sub munu/(x) is a coordinate-gauge field tensor if and only if it satisfies the restricted set of Bianchi identities epsilon/sup munusigmalambda/x/sub sigma/D/sup rho/(F)*F/sub rholambda/ = 0, D = partial+(A(F),x). These results permit us to transform the functional integral for the vacuum-to-vacuum amplitude Z(J) for the gauge theory to a form in which the potentials are completely eliminated in terms of the field strengths. When the Bianchi constraints are eliminated using a set of Lagrange multiplier fields lambda/sub sigma/(x), the F 's can be integrated out completely to obtain a form of the theory which appears to be useful for strong coupling.
