Abstract
Cross sections for e (+) p charged current deep inelastic scattering at a centre-of-mass energy of 318 GeV have been determined with an integrated luminosity of 60.9 pb(-1) collected with the ZEUS detector at HERA. The differential cross sections dsigma/dQ(2), dsigma/dx and dsigma/dy for Q(2) > 200 GeV are presented. In addition, d(2)sigma/d x d Q(2) has been measured in the kinematic range 280 GeV2 < Q(2) < 17 000 Gev(2) and 0.008 << x < 0.42. The predictions of the Standard Model agree well with the measured cross sections. The mass of the W boson propagator is determined to be M-W = 78.9 +/- 2.0 (stat.) +/- 1.8(syst.)(-1.8)(+2.0) (PDF) GeV from a fit to dsigma/dQ(2). The chiral structure of the Standard Model is also investigated in terms of the (1-y)(2) dependence of the double-differential cross section. The structure-function F-2(CC) has been extracted by combining the measurements presented here with previous ZEUS results from e(-)p scattering, extending the measurement obtained in a neutrino-nucleus scattering experiment to a significantly higher Q(2) region.
