On the gauge dependence of spectral functions

journal contribution
posted on 2023-05-18, 05:03 authored by Robert DelbourgoRobert Delbourgo, Keck, BW
An integral relation is derived between charged source spectral functions in photon gauges differing by longitudinal terms akmu knu /k4. The a dependences of the spectral and Green functions supplied by the gauge technique automatically satisfy these integral relations.
