We use the [ital S]-matrix pinch technique to derive to one loop order an effective renormalizable self-energy for the [ital W] gauge boson, when the theory is quantized in the unitary gauge. We then show that this amplitude is identical to the [xi]-independent [ital W] self-energy previously constructed by applying the pinch technique in the context of the renormalizable [ital R][sub [xi]] gauges.
