摘要：
A new method is employed to measure the neutral current cross-section up to Bjorken x values of 1 with the ZEUS detector at HERA using an integrated luminosity of 187 pb − 1 of electron–proton collisions and 142 pb − 1 of positron–proton collisions, at a centre-of-mass energy of 318 GeV. Cross-sections have been extracted for Q2 > 575 GeV2. A much improved precision with respect to the previous ZEUS publication, which used only 16.7 pb − 1 of electron–proton collisions and 65.1 pb − 1 of positron–proton collisions, is achieved, owing to the large data sample and improved kinematic reconstruction methods. The measurement is well-described by different theory predictions.
