Abstract

Cross sections for e(-)p neutral current deep inelastic scattering have been measured at a centre-of-mass energy of 318 GeV using an integrated luminosity of 15.9 pb(-1) collected with the ZEUS detector at HERA. Results on the double-differential cross-section d(2)sigma/dx dQ(2) in the range 185 < Q(2) < 50 000 GeV(2) and 0.0037 < x < 0.75, as well as the single-differential cross-sections dsigma/dQ(2), dsigma/dx and dsigma/dy for Q(2) > 200 GeV(2), are presented. To study the effect of Z-boson exchange, dsigma/dx has also been measured for Q(2) > 10 000 GeV(2). The structure function xF(3) has been extracted by combining the e(-)p results presented here with the recent ZEUS measurements of e(+)p neutral current deep inelastic scattering. All results agree well with the predictions of the Standard Model.
