FULL ONE-LOOP SUPERSYMMETRIC QUANTUM EFFECTS ON M_w

We present a detailed numerical analysis of a fully-fledged computation of one-loop supersymmetric quantum effects on the mass of the weak gauge boson W ± in the standard on-shell renormalization scheme based on the input parameters (G F , α, M Z ). The importance of the process-dependent contributions as compared to the universal effects is assessed. The final numerical results show that in large regions of parameter space the potential radiative shifts [Formula: see text] could be within the level of precision expected at LEP II, depending on the model considered. A comparison is made with other renormalization frameworks.
