Abstract
The contribution to precision electroweak measurements due to TeV phys ics which couples primarily to the W+/- and Z bosons may be parametriz ed in terms of the three ''oblique correction'' parameters, S, T, and U. We extend this parametrization to physics at much lower energies, g reater 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.
