Higgs Decay $H \to \gamma\gamma$ through a W Loop: Difficulty with Dimensional Regularization

Since the photon has no mass, it does not couple directly to the Higgs particle. This implies that the one-loop correction to the decay H --> \gamma\gamma\ is necessarily finite. Therefore, this correction should be calculable without introducing either regularization or ghosts. Such a calculatio...
