摘要：
Deep inelastic charged current reactions have been studied in e(+)p collisions at a center of mass energy of 300 GeV in the kinematic region 400 < Q(2) < 40000 GeV2 using 46.6 pb(-1) of data from the ZEUS detector at HERA. The preliminary differential cross-section is presented as a function of the variable Q(2), and is found to agree with the Standard Model predictions. Using the measured Q(2) distribution the W boson mass is determined to be M-W = 78.6(-2.4)(+2.5) [stat] (+3.3)(-3.0) [syst].
