Field-dependent quantum gauge transformation
Abstract
In this paper we generalize the quantum gauge transformation of Maxwell theory obtained through gaugeon formalism. The generalization is made by making the bosonic transformation parameter field-dependent. The Jacobian of vacuum functional under field-dependent quantum gauge transformation is calculated explicitly. We show that the quantum gauge transformation with a particular choice of field-dependent parameter connects the gaugeon actions of Maxwell theory in two different gauges. We establish the result by connecting two well-known gauges, namely, Lorentz gauge and axial gauge.
