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, Q (2), between 125 and 20 000 GeV(2). The jets were reconstructed with the k (T) cluster algorithm in the Breit reference frame and selected by requiring their transverse energies in the Breit frame, E(jet) (T,B), to be larger than 8 GeV. In addition, the invariant mass of the dijet system, M(jj,) was required to be greater than 20 GeV. The cross sections are described by the predictions of next-to-leading-order QCD.

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, Q (2), between 125 and 20 000 GeV(2). The jets were reconstructed with the k (T) cluster algorithm in the Breit reference frame and selected by requiring their transverse energies in the Breit frame, E(jet) (T,B), to be larger than 8 GeV. In addition, the invariant mass of the dijet system, M(jj,) was required to be greater than 20 GeV. The cross sections are described by the predictions of next-to-leading-order QCD.Pubblicazioni consigliate
