We study azimuthal angular correlations in 3-parton production in DIS at small Bjorken x. We compute the 3-parton production cross-section in DIS utilizing spinor helicity techniques and show that the angular correlations among the 3 final state partons exhibit the behavior expected from gluon saturation dynamics; broadening and disappearing of the away side peaks, similar to that observed in di-hadron production in deuteron-gold collisions in RHIC. We outline the possible connections and extensions to other high energy processes in QCD.
