Azimuthal correlations of forward di-hadrons in d+Au collisions at RHIC in the Color Glass Condensate

TL;DR

This paper uses the Color Glass Condensate theory to successfully describe azimuthal correlations of forward di-hadrons in d+Au collisions at RHIC, providing evidence for saturation effects in the nuclear wave function.

Contribution

It presents a novel application of the Color Glass Condensate framework with non-linear evolution equations to interpret experimental di-hadron correlation data at RHIC.

Findings

Good agreement with experimental data on azimuthal correlations

Evidence supporting saturation effects in nuclear wave functions

Validation of the CGC approach for small-x physics

Abstract

We present a good description of recent experimental data on forward di-hadron azimuthal correlations measured in deuteron-gold collisions at RHIC, where monojet production has been observed. Our approach is based on the Color Glass Condensate effective theory for the small-x degrees of freedom of the nuclear wave function, including the use of non-linear evolution equations with running QCD coupling. Our analysis provides further evidence for the presence of saturation effects in RHIC data.
