W boson mass and Properties

AIP Conference Proceedings 792 (2005) 559-562

Abstract:

Measurements of the W boson determine fundamental parameters of the standard model and test its internal consistency at the level of radiative corrections. In particular, the W boson mass constrains the mass of the unobserved Higgs boson through loop corrections, and the W boson width indirectly determines elements of the CKM matrix defining quark generational mixing in the electroweak interactions. The CDF Collaboration has analyzed ≈200 pb -1 of s=1.96TeV pp̄ collision data and determined the uncertainty on its W boson mass measurement to be 76 MeV. The DØ Collaboration has directly measured the W boson width to be Γ W = 2.011 ± 0.09(stat.)±0.107(syst.) GeV using 177 pb -1 of W → ev data. © 2005 American Institute of Physics.

Abstract:

Multijet production rates in neutral current deep inelastic scattering have been measured in the range of exchanged boson virtualities 10 < Q 2 < 5000 GeV2. The data were taken at the ep collider HERA with centre-of-mass energy √s = 318 GeV using the ZEUS detector and correspond to an integrated luminosity of 82.2pb-1. Jets were identified in the Breit frame using the kT cluster algorithm in the longitudinally invariant inclusive mode. Measurements of differential dijet and trijet cross sections are presented as functions of jet transverse energy (ET,Bjet), pseudorapidity (ηLAB jet) and Q2 with ET,Bjet > 5 GeV and -1 < ηLABjet < 2.5. Next-to-leading-order QCD calculations describe the data well. The value of the strong coupling constant αs(MZ), determined from the ratio of the trijet to dijet cross sections, is αs(MZ) = 0.1179 ± 0.0013 (stat.)-0.0046-0.0028 (exp.) -0.0046+0.0064 (th.). © Springer-Verlag / Società Italiana di Fisica 2005.
