Precision Measurement of sin²theta_W from nu-N Scattering at NuTeV and Direct Measurements of M_W

We present the preliminary result of sin^2theta_W from nu-N deep inelastic scattering experiment, NuTeV, at Fermilab. This measurement of sin^2theta_W comes from measuring the Paschos-Wolfenstein parameter R-=sigma_NC^nu-sigma_NC^nubar/(sigma_CC^{nu}-sigma_CC^nubar), using separate beams of nu and nubar, utilizing the SSQT. The resulting value of sin^2\theta_W^(on-shell) is $0.2253\pm0.0019(stat)\pm0.0010(syst)$. This value is equivalent to the mass of the W boson, M_W=80.26\pm0.11 GeV/c^2. We also summarize the direct measurements of M_W from the Tevatron pbar-p collider experiments, D\O and CDF. Combining these two direct measurements yields M_W=80.37\pm0.08 GeV/c^2.
