摘要：

The contribution to precision electroweak measurements due to TeV physics which couples primarily to the W+/- and Z bosons may be parametrized in terms of the three ''oblique correction'' parameters, S, T, and U. We extend this parametrization to physics at much lower energies, greater than or similar to 100 GeV, and show that in this more general case neutral-current experiments are sensitive to only two additional parameters. A third new parameter enters into the W+/- width.
