Spinor helicity methids in DIS at small x: 3-parton production
Résumé
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.
