# The gluon condensation at high energy hadron collisions

## TL;DR

This paper reveals that gluon distributions in high-energy hadron collisions evolve into a condensed state with a sharp peak, driven by chaotic nonlinear QCD dynamics, leading to novel phenomena like gluon-jet bursts and energy limits in colliders.

## Contribution

It uncovers a new gluon condensation phenomenon caused by chaotic solutions in nonlinear QCD evolution, challenging existing saturation models and predicting novel high-energy collision effects.

## Key findings

- Gluon distribution becomes sharply peaked at a critical momentum.
- Chaotic solutions induce gluon condensation and novel effects.
- Potential implications for astrophysics and collider energy limits.

## Abstract

We report that the saturation/CGC model of gluon distribution is unstable under action of the chaotic solution in a nonlinear QCD evolution equation, and it evolves to the distribution with a sharp peak at the critical momentum. We find that this gluon condensation is caused by a new kind of shadowing-antishadowing effects, and it leads to a series of unexpected effects in high energy hadron collisions including astrophysical events. For example, the extremely intense fluctuations in the transverse-momentum and rapidity distributions of the gluon jets present the gluon-jet bursts; a sudden increase of the proton-proton cross sections may fill the GZK suppression; the blocking QCD evolution will restrict the maximum available energy of the hadron-hadron colliders.
