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

TL;DR

This paper examines evidence for QCD saturation effects in d+Au collisions at RHIC, analyzing forward hadron yields and azimuthal correlations, and compares the Color Glass Condensate model with alternative approaches.

Contribution

It provides a detailed analysis of saturation effects in d+Au collisions and discusses different theoretical frameworks beyond the CGC model.

Findings

Evidence supports the presence of saturation effects in RHIC data.

Forward hadron yields show suppression consistent with saturation.

Azimuthal correlations indicate modifications due to saturation phenomena.

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.
