W/Z and Diboson Properties

Most recent measurements of properties of $W$ and $Z$ gauge bosons at hadron colliders are presented. The measurements were performed by ATLAS, CMS, and LHCb collaborations with proton-proton collisions at the LHC and by CDF and D0 collaborations with proton-antiproton collisions at the Tevatron. Center-of-mass energy was 7 TeV and 1.96 TeV at the LHC and Tevatron respectively. Integrated luminosity ranges from 35 pb$^{-1}$ to 1.02 pb$^{-1}$ for LHC and from 0.2 fb$^{-1}$ to 7.1 fb$^{-1}$ for Tevatron.

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.
