Abstract

Dijet cross sections in neutral current deep inelastic ep scattering have been measured in the range 10<Q²<10⁴ GeV² with the ZEUS detector at HERA using an integrated luminosity of 38.4 pb^-1. The cross sections, measured in the Breit frame using the k_T jet algorithm, are compared with next-to-leading-order perturbative QCD calculations using proton parton distribution functions. The uncertainties of the QCD calculations have been studied. The predictions are in reasonable agreement with the measured cross sections over the entire kinematic range.
