We introduce the azimuthal correlation for the deep inelastic scatteringprocess. We present the QCD prediction to the level of next-to-leading logresummation, matching to the fixed order prediction. We also estimate theleading non-perturbative power correction. The observable is compared with theenergy-energy correlation in e+e- annihilation, on which it is modelled. Theeffects of the resummation and of the leading power correction are both quitelarge. It would therefore be particularly instructive to study this observableexperimentally.Comment: 33 pages, 4 figures, JHEP class included. One figure and some clarifications adde
