Limiting fragmentation in the dilute Glasma

TL;DR

This paper investigates the limiting fragmentation phenomenon in the dilute Glasma, revealing how the longitudinal structure of colliding nuclei influences particle production and how scalar observables exhibit this behavior.

Contribution

It provides new insights into the local longitudinal scaling in the dilute Glasma and analyzes the effects of nuclear color charge correlations on fragmentation.

Findings

Scalar observables in the dilute Glasma show limiting fragmentation behavior.

The field strength tensor transforms via Lorentz boosts with changing collision energy.

The fragmentation region is dominated by the longitudinal structure of one nucleus.

Abstract

We discuss the local longitudinal scaling behavior of the dilute Glasma. We gain insight into how the fragmentation region is dominated by the longitudinal structure of one of the two colliding nuclei in heavy-ion collisions and study the effect of the correlation scales of the nuclear color charge distributions. We compare with results from the full dilute Glasma framework and analyze the rapidity limits of the fragmentation region. From our findings, it follows that all scalar observables that can be constructed out of the dilute Glasma field strength tensor show limiting fragmentation behavior and the field strength tensor itself transforms locally via Lorentz boosts when changing the collision energy.
