Beyond S, T and U
摘要
The contribution to precision electroweak measurements due to TeV physics which couples primarily to the and bosons may be parameterized in terms of the three `oblique correction' parameters, S, T and U. We extend this parameterization to physics at much lower energies, GeV, and show that in this more general case three more parameters are required (which we call V, W and X). Only two of these appear in neutral-current experiments, while the third new parameter enters into the width.
