Strange Sea and alpha-s Measurements from nu-N Deep Inelastic Scattering at CCFR/NuTeV

We present the latest Next-to-Next-Leading order strong coupling constant, alpha-s, extracted from Gross-Llewellyn-Smith sum rule. The value of alpha-s from this measurement, at the mass of Z boson, is alpha-s^{NNLO}(M_Z**2)=0.114^{+0.009}_{-0.012}. We discuss the previous strange sea quark measurement from the CCFR experiment and the prospects for improvements of the measurement in the NuTeV experiment.

Recent QCD results in nu-N Deep Inelastic Scattering at CCFR/NuTeV

We present recent QCD results in nu-N scattering at the Fermilab CCFR/NuTeV experiments. We present the latest Next-to-Next-Leading order strong coupling constant, alpha-s, extracted from Gross-Llewellyn-Smith sum rule. The value of alpha-s from this measurement, at the mass of Z boson, is alpha-s^{NNLO}(M_Z**2)=0.114^{+0.009}_{-0.012}. We also present a preliminary result of the CCFR F_2 at large-x. This measurement of F_2 is compared to other experiments and various models that provide nuclear effects. We discuss the previous strange sea quark measurement from the CCFR experiment and the prospects for improvements of the measurement in the NuTeV experiment.

Precision Measurement of sin^2theta_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^2θ_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, DØand CDF. Combining these two direct measurements yields M_W=80.37\pm0.08 GeV/c^2.
