Single and double inclusive particle production in d+Au collisions at RHIC, leading twist and beyond

Abstract

We discuss the evidence for the presence of QCD saturation effects in the data collected in d+Au collisions at RHIC. In particular we focus our analysis on forward hadron yields and azimuthal correlations. Approaches alternative to the CGC description of these two observables are discussed in parallel.
