Abstract
Cross sections for e(-)p charged current deep inelastic scattering have been measured at a centre-of-mass energy of 318 GeV with an integrated luminosity of 16.4 pb(-1) using the ZEUS detector at HERA. Differential cross sections dsigma/dQ(2), dsigma/dx and dsigma/dy are presented for Q(2) > 200 GeV(2). In addition, d(2)sigma/(dxdQ(2)) was measured in the kinematic range 280 GeV(2) < Q(2) < 30000 GeV(2) and 0.015 < x < 0.42. The predictions of the Standard Model agree well with the measured cross sections. The mass of the W boson, determined from a fit to dsigma/dQ(2), is M(W) = 80.3 +/- 2.1 (stat.) +/- 1.2(syst.) +/- 1.0(PDF) GeV.
