Abstract

Based on the color dipole QCD approach we discuss the multiple scattering mechanism (MSM) of suppression of back-to-back azimuthal correlations of high p_T forward dijets in DIS off nuclei. We quantify the effect in terms of acoplanarity/decorrelation momentum of jets. For hard dijets the decorrelation momentum is found to be of the order of the nuclear saturation momentum Q_A. Minijets with the transverse momentum below the saturation scale are proved to be completely decorrelated. The analysis of DIS indicates that in heavy ion collisions the contribution of MSM to the reactions dynamics can be of the order of magnitude of the decorrelation effect observed at RHIC.
