Description
Measurements of low-energy neutral current parameters and vector-boson masses are sensitive to the top quark mass mt via one-loop radiative corrections in the standard model. Assuming the Higgs mass MH = MZ, the combination of present data imposes mt < 153 GeV at the 68.3% CL if the charm quark mass mc=1.45 GeV, or mt < 185 GeV if mc is left free. The upper limit on mt is only weakly sensitive to MH. The overall χ2 increases slightly with MH, but there is no significant upper bound on MH. (orig.)
