Abstract:
:The implications of recent precision Z-pole, W mass, and weak neutral current data for testing the standard electroweak model, constraining that t quark and Higgs masses, αs (MZ), and grand unification are discussed. A fit to all data yields sin(2)θw(MZ)= 0.2325 ± 0.0024 (on-shell), where the uncertainties are mainly from mt. In the standard model one predicts mt (+17+15) -23-17 GeV, where the central value assumes MH± 50 GeV (-) or 1 TeV (+). In the minimal supersymmetric extension of the standard model (MSSM) one predicts mt= 138(+20) -25± 5 GeV, where the difference is due the light Higgs scalar expected in the MSSM. There is no significant constraint on MH until mt is known independently. Including perturbative estimates of the O(ααsm(2) t) corrections, these values increase by ∼ 5 GeV.
