Abstract

Single- and double-differential inclusive dijet cross sections in neutral current deep inelastic ep scattering have been measured with the ZEUS detector using an integrated luminosity of 374 pb−1. The measurement was performed at large values of the photon virtuality, Q2, between 125 and 20 000 GeV2. The jets were reconstructed with the kT cluster algorithm in the Breit reference frame and selected by requiring their transverse energies in the Breit frame, \(E^{\rm jet}_{T,{\rm B}}\), to be larger than 8 GeV. In addition, the invariant mass of the dijet system, \(M_{\rm jj}\), was required to be greater than 20 GeV. The cross sections are described by the predictions of next-to-leading-order QCD.
