We report ? measurement of the dijet production cross flection in neutral current deep inelastic scattering with the ZEUS detector at the HERA ep collider. Dijet events are identified with the cone algorithm and the results ore compared to next-to-leading order pcrturbativc QCD calculations. The measurement!) are sensitive to the gluon density of the proton in the x range between 10~3 and 10~l.
