Abstract
Cross sections for e+ p neutral current deep inelastic scattering have been measured at a center-of-mass energy of ās = 318 GeV with the ZEUS detector at HERA using an integrated luminosity of 63.2 pb -1. The double-differential cross section, d2Ļ/ dxdQ2, is presented for 200 GeV2 < Q2 < 30 000 GeV2 and for 0.005 < x < 0.65. The single-differential cross sections dĻ/dQ2, dĻ/dx and dĻ/dy are presented for Q2 > 200 GeV2. The effect of Z-boson-exchange is seen in dĻ/dx measured for Q2 > 10 000 GeV2. The data presented here were combined with ZEUS e+ p neutral current data taken at ās = 300 GeV and the structure function F2 em was extracted. All results agree well with the predictions of the Standard Model.
