Spectrum of diffractively produced gluons in onium-nucleus collisions

TL;DR

This paper calculates the spectrum of diffractively produced gluons in onium-nucleus collisions, revealing dependence on nuclear size and energy, which can help probe the low-x structure of nuclear matter at high-energy colliders.

Contribution

It provides a theoretical calculation of gluon spectra in onium-nucleus collisions, highlighting their dependence on nuclear size and energy for the first time.

Findings

Gluon spectrum depends on nucleus atomic number A and energy/rapidity.

Characteristic A and energy dependence can probe low-x nuclear structure.

Applications discussed for RHIC, LHC, and EIC experiments.

Abstract

We calculate spectrum of diffractively produced gluons in onium-heavy nucleus collisions at high energies. We show that it exhibits a characteristic dependence on nucleus atomic number A and energy/rapidity. We argue that this dependence offers a unique possibility for determining the low-x structure of nuclear matter. Applications to RHIC, LHC and EIC experimental programs are discussed.
