# Effect of non-eikonal corrections on azimuthal asymmetries in the Color Glass Condensate

## TL;DR

This paper investigates how relaxing the shockwave approximation affects azimuthal correlations in gluon production within the Color Glass Condensate framework, revealing significant non-eikonal effects at RHIC energies but negligible at LHC energies.

## Contribution

It introduces non-eikonal corrections into the analysis of azimuthal asymmetries in the CGC, providing a more detailed understanding of gluon correlations beyond the shockwave approximation.

## Key findings

- Non-eikonal effects generate both even and odd harmonics in azimuthal distributions.
- These effects are significant at RHIC energies but diminish at LHC energies.
- The study offers insights into energy dependence of gluon correlation structures.

## Abstract

We analyse the azimuthal structure of two gluon correlations in the Color Glass Condensate including those effects that result from relaxing the shockwave approximation for the target. Working in the Glasma graph approach suitable for collisions between dilute systems, we compute numerically the azimuthal distributions and show that both even and odd harmonics appear. We study their dependence on model parameters, energy of the collision, pseudorapidity and transverse momentum of the produced particles, and length of the target. While the contribution from non-eikonal corrections vanishes with increasing collision energy and becomes negligible at the energies of the Large Hadron Collider, it is found to be sizeable up to top energies at the Relativistic Heavy Ion Collider.
