AbstractAbstract
[en] We present a new measurement of the W mass using the W → eν data from the D0 forward detectors at the Fermilab Tevatron p anti p Collider. This is the first measurement of the W mass with electron candidates in the range 1.5 <| η |< 2.5. We present measurements of the W mass using the transverse mass, the electron transverse momentum and the neutrino transverse momentum, and the combined result using all three techniques. The combination of the forward detector measurement with the previous measurements using the central detector gives a new precise measurement of the W mass from D0

AbstractAbstract
[en] It is well known that a radiation amplitude zero (RAZ) occurs in radiative W decay (W- → d bar uγ or W- → e bar νγ). This RAZ can be used to measure the magnetic moment of the W boson to see if it has the gauge-theory value κ = 1, and, in this way, test the Standard Model (SM). In this paper we prove that the RAZ in this process is unique and, thus, the experimental discovery of any zero in this process implies that there exists a RAZ and, hence, κ = 1. 5 refs

AbstractAbstract
[en] We present a preliminary measurement of the electron angular distribution parameter α2 in W → eν events using data collected by the D0 detector during the 1994-1995 Tevatron run. We compare our results with next-to- leading order perturbative QCD, which predicts an angular distribution of (1α1 cosθ* +α2 cosθ*), where θ* is the angle between the charged lepton and the antiproton in the Collins-Soper frame. In the presence of QCD corrections, the parameters α1 and α2 become functions of pWT , the W boson transverse momentum. We present the first measurement of α2 as a function of pWT. This measurement is of importance, because it provides a test of next-to-leading order QCD corrections which are a non-negligible contribution to the W mass measurement

AbstractAbstract
[en] This paper presents measurements of the mass of the W vector boson from the CDF and D0 experiments using data collected at √s = 1.8 TeV during the 1994- 1995 data taking run. CDF finds a preliminary mass of MW = 80.43 ± 0.16 GeV and D0 measures a mass of MW = 80.44 ± 0.12 GeV

AbstractAbstract
[en] Preliminary data from the New Muon Collaboration (NMC) allow a precise evaluation of Ip-n(x) from a given integral formula for values of x down to 0.004. As x → 0, this integral should converge to a value Ip-n(0) = 1/3 (Gottfried sum rule) if the light sea-quark distributions are equal. The NMC value Ip-n(0.004) = 0.23 ± 0.03, though appearing to be well short of 1/3, is quite consistent with modern estimates for parton distributions extracted from a wide range of data. These parton distributions are also found to reproduce the W± rapidity asymmetry recently measured by a European collaboration. (author)

AbstractAbstract
[en] This article describes recent measurements of the W mass by the CDF and D0 Collabo-rations. CDF obtains a preliminary result of 80.473 and ± 0.113 GeV for the W mass in the electron channel and D0 reports a preliminary result of 80.766 and ± 0.234 GeV for electrons in the more forward (Endcap) rapidities. When combined with all previous measurements, the current average for the W mass measured at the Tevatron is 80.450 and ± 0.063 GeV
