摘要：

We present an analysis of the constraints on one-loop "oblique" (vacuum polarization) electroweak radiative corrections imposed by precise data from LEP and other experiments. We present these constraints in full three-dimensional S, T, U space, using a complete set of low-energy data, and LEP data on heavy flavour production as well as leptons and hadrons. We take into account the uncertain top quark and Higgs boson contributions to non-oblique radiative corrections and discuss quantitatively variations associated with higher-order effects. We compare our bounds with recent estimates in a number of different technicolour scenarios.
