UV-divergent part of the vacuum polarization tensor in the temporal gauge with the LM prescription. BRS identities

The one-loop UV-divergent contribution to the vacuum polarization tensor (Πμνab) is computed in a temporal-planar gauge using the LM prescription that gives the correct exponential behaviour for the Wilson loop. Its dependence on the gauge parameter and on the magnitude of the unphysical vectors n and n' - introduced by the LM prescription - is derived from the BRS invariance of the theory and shown to be consistent with our result for Πμνab.
