چکیده
We discuss a novel approach to renormalize the Electroweak Sector of the Standard Model, in which sin 2 θ lept ef f , measured at the Z 0 peak, is identified with the basic renormalized electroweak mixing parameter. This approach shares the desirable convergence properties of the M S scheme and provides a framework for calculations that are strictly independent of the electroweak scale in finite orders of perturbation theory. We illustrate the method with updated precise calculations of sin 2 θ lept ef f and M W , as functions of M H , and comment on the implications of these calculations for the Higgs boson search and the theoretical prediction of M W .
