A Departure from Prediction: Measurement of Electroweak Parameters at NuTeV

The NuTeV collaboration has extracted the electroweak parameter, sin2thw, from the measurement of the ratios of neutral current to charged current neutrino and antineutrino cross sections. We find that our measurement, while in agreement with previous neutrino electroweak measurements, is not consistent with predictions. To facilitate interpretation of this result, model independent analyses are also presented.
