Abstract

We have examined the evidence for the electroweak radiative corrections in the LEP precision data along with the intriguing possibility that the QED corrections only may be sufficient to fit the data. We find that the situation is very sensitive to the precise value of M_W. While the world average value of M_W strongly favors nonvanishing electroweak radiative corrections, the QED corrections alone can account for the data within 2σ in the context of the standard model. We discuss how the precision measurements of M_W can provide a decisive test for the standard model with radiative corrections and give a profound implication for the existence of t-quark and Higgs scalar.
