Forward particle production in d-Au collisions

Single particle observables (inclusive spectra and nuclear modification factors) in d-Au collisions at RHIC are often quoted as evidence for the Color Glass Condensate (CGC), condisering the suppressed production at forward rapidities. Indeed, these kinematics probe partons in the nucleus that have a small fraction of momentum x, and it is natural to expect non-linear QCD to play a role. The next d-Au run at RHIC will allow to measure more observables and enable further tests of the CGC picture. In this seminar, I will consider forward inclusive dijets and focus on correlations in azimuthal angle. In my calculation, I include both multiple scattering and non-linear QCD evolution at small-x. I obtain that the azimuthal angle distribution is peaked back to back and broadens as the momenta of the measured particles gets closer to the saturation scale.
