                                    Resum

  The consistent description of unstable particles within the framework of
      perturbative gauge field theories necessitates the definition and
   resummation of off-shell Green's functions, which must respect several
   crucial physical requirements. We present a solution to this problem at
 one-loop, using arguments of gauge-invariance, analyticity, unitarity, and
                             renormalisability.
