A new method is employed to measure the neutral current cross section up to Bjorken-x values of one with the ZEUS detector at HERA using an integrated luminosity of 65.1 pb-1 for e+p collisions and 16.7 pb-1 for e-p collisions at sqrt(s)=318 GeV and 38.6 pb-1 for e+p collisions at sqrt(s)=300 GeV . Cross sections have been extracted for Q2≥648 GeV^2 and are compared to predictions using different parton density functions. For the highest x bins, the data have a tendency to lie above the expectations using recent parton density function parametrizations.

Abstract

A new method is employed to measure the neutral current cross section up to Bjorken-x values of one with the ZEUS detector at HERA using an integrated luminosity of 65.1 pb-1 for e+p collisions and 16.7 pb-1 for e-p collisions at sqrt(s)=318 GeV and 38.6 pb-1 for e+p collisions at sqrt(s)=300 GeV . Cross sections have been extracted for Q2≥648 GeV^2 and are compared to predictions using different parton density functions. For the highest x bins, the data have a tendency to lie above the expectations using recent parton density function parametrizations.
