Precision measurement of sin(squared) {theta}{sub W} from {nu}-N scattering at NuTeV and direct measurements of M{sub W}
We present the preliminary result of sin{sup 2}{theta}{sub W} from {nu}-N deep inelastic scattering experiment, NuTeV, at Fermilab. This measurement of sin{sup 2}{theta}{sub W} comes from measuring the Paschos-Wolfenstein parameter R=({sigma}{sup {nu}}{sub NC}-{sigma}{sup {anti {nu}}}{sub NC}), using separate beams of {nu} and {anti {nu}}, utilizing the SSQT. The resulting value of sin{sup 2}{theta}{sub W}{sup on-shell} is 0.2253 {+-} 0.0019(stat) {+-} 0.0010(syst). This value is equivalent to the mass of the W boson, M{sub W} = 80.26 {+-} 0.11 GeV/c{sup 2}. We also summarize the direct measurements of M{sub W} from the Tevatron {anti p}p collider experiments, D0 and CDF. Combining these two direct measurements yields M{sub W} = 80.37 {+-} 0.08 GeV/c{sup 2}.
