  The Z-pole data from e+e- colliders and results from the NuTeV experiment at
Fermilab can be brought into agreement if (1) the neutrino-Z couplings were
suppressed relative to the Standard Model (SM), and (2) the Higgs boson were
much heavier than suggested by SM global fits. However, increasing the Higgs
boson mass will move the theoretical value of the W mass away from its
experimental value. A large and positive U parameter becomes necessary to
account for the difference. We discuss what type of new physics may lead to
such values of U.
