Spinor helicity methods in high-energy factorization: efficient momentum-space calculations in the Color Glass Condensate formalism

Résumé

We use the spinor helicity formalism to calculate the cross section for production of three partons of a given polarization in Deep Inelastic Scattering (DIS) off proton and nucleus targets at small Bjorken x . The target proton or nucleus is treated as a classical color field (shock wave) from which the produced partons scatter multiple times. We reported our result for the final expression for the production cross section and studied the azimuthal angular correlations of the produced partons in [1] . Here we provide the full details of the calculation of the production cross section using the spinor helicity methods.
