摘要
We report the results of a global fit to m(t) and M(H) within the standard model using the latest LEP and other precision electroweak data. We find 92 < m(t) < 147 GeV and 1.4 < M(H) < 160 GeV (68% CL) if all data are included, although the upper limit on M(H) would be relaxed if (more conservatively) the troublesome measurements of the hadron-to-lepton ratio on the Z0 peak are omitted from the fit. These ranges of m(t) and M(H) are consistent with the limits from direct searches, which is an impressive and nontrivial check on the consistency of the standard model beyond the tree level. Our analysis of radiative corrections disfavours a strongly-interacting Higgs system, as well as naive ttBAR condensate versions of the standard model. The top quark and the Higgs boson are probably both close to our present experimental reach.
