Erratum: Initial fields and instability in the classical model of the heavy-ion collision

TL;DR

This paper corrects an analytical expression for energy density in a heavy-ion collision model and discusses the implications of the correction on the understanding of initial fields and instability.

Contribution

It identifies and corrects a mistake in the analytical formula for energy density, clarifying the role of randomness and longitudinal extent of color sources.

Findings

Corrected the energy density expression by multiplying by 16

Highlighted the impact of the correction on model predictions

Discussed the subtle issues in the treatment of color source randomness

Abstract

We correct a mistake in the analytical expression for the energy density given in Phys. Rev. C76, 021902 (2007) [arXiv:0704.3625 [hep-ph]]. The expression should be multiplied by 16. One question then arises; how could it be possible to explain this difference between the analytical and numerical results in the same model if both are correct? We find a subtle problem in the treatment of the randomness of the color source along the longitudinal direction and the treatment of the longitudinal extent of the color source.
