Abstract

We use spinor helicity methods to calculate the azimuthal
angular correlations between three partons produced in Deep Inelstic
Scattering (DIS) at small Bjorken $x$. We show that gluon saturation
effects in the proton or nucleus target lead to a broadening and
disappearance of the two away side peaks. We show how our results
may be used to include the effects of fully coherent cold matter
energy loss in di-jet production in DIS at small $x$
