摘要：

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), alpha, Mz). 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 deltaM(W)SUSY could be within the level of precision expected at LEP II, depending on the model considered. A comparison is made with other renormalization frameworks.
