Rapidity and centrality dependence of azimuthal correlations in high energy d+Au collisions

TL;DR

This paper investigates azimuthal correlations in high-energy deuteron-gold collisions, demonstrating that gluon saturation effects in the Color Glass Condensate can explain the observed suppression of back-to-back peaks.

Contribution

It provides a quantitative explanation for azimuthal correlation modifications using gluon saturation in the Color Glass Condensate framework.

Findings

Back-to-back peak depletion explained by gluon saturation

Correlation patterns vary with rapidity and centrality

Supports CGC as a valid description at high energies

Abstract

We discuss azimuthal correlations in $dAu$ collisions at different rapidities and centralities and argue that experimentally observed depletion of the back-to-back peak can be quantitatively explained by gluon saturation in the Color Glass Condensate of the Gold nucleus.
