The Abelian Antighost Equation for The Standard Model in the `t   Hooft-Background Gauge
  In this paper we study the Abelian Anti-ghost equation for the Standard Model quantized in the 't Hooft-Background gauge. We show that this equation assures the non-renormalization of the abelian ghost fields and prevents possible abelian anomalies.
