Light-Front Analysis of pi^{-} Mesons Produced in Mg - Mg Collisions at 4.3 a Gev/c

TL;DR

This study analyzes pi^{-} mesons produced in Mg-Mg collisions at 4.3 a GeV/c using light-front analysis, revealing thermalization aspects and validating the Quark Gluon String Model with experimental data.

Contribution

It introduces a light-front analysis method for secondary pions in Mg-Mg collisions and compares thermalization assumptions with experimental data and QGSM predictions.

Findings

Phase space division supports thermal equilibrium in one part.

Extracted temperatures align with other experimental results.

QGSM predictions agree satisfactorily with data.

Abstract

Light-front analysis of pi^{-} mesons in Mg-Mg collisions is carried out. The phase space of secondary pions is naturally divided into two parts in one of which the thermal equilibration assumption seems to be in a good agreement with data. Corresponding temperatures are extracted and compared to the results of other experiments. The experimental results have been compared with the predictions of the Quark Gluon String Model (QGSM) and satisfactory agreement between the experimental data and the model has been found.
