Odd Azimuthal Anisotropy of the Glasma for pA Scattering

TL;DR

This paper analytically derives the odd azimuthal anisotropy in the Glasma for proton-nucleus collisions, focusing on the first non-trivial proton source term in the classical Yang-Mills framework.

Contribution

It provides the first analytical calculation of odd azimuthal anisotropy in the Glasma, expanding the proton sources of color charge in a large nucleus limit.

Findings

Analytical expression for odd azimuthal anisotropy in pA collisions.

Valid in the regime where produced particle momenta exceed the proton saturation momentum.

First non-trivial term in proton source expansion derived.

Abstract

In this paper we analytically extract the odd azimuthal anisotropy in the Classical Yang-Mills equations for the Glasma for pA collisions. We compute the first non-trivial term in the expansion of the proton sources of color charge. The computation is valid in the limit of a large nucleus when the produced particle momenta are larger than the saturation momentum of the proton.
