摘要：
Inclusive e+p cross sections for neutral and charged current deep inelastic scattering have been determined by the H1 and ZEUS collaborations at HERA. The data were recorded in 1999 and 2000 at a center of mass energy of 318 GeV with an integrated luminosity of 65.2 pb–1 and 60.9 pb–1, respectively. Taking into account previously published e±p neutral current data the structure functions F2 and xF3 were extracted. FL was determined by extending the measurement to small scattered positron energies. The quark singlet distribution F2CC was extracted for the first time at HERA by combining e+p and e–p charged current cross sections. All results are well described by Standard Model expectations.
