Bose-Einstein correlations and the transition time from QCD plasma to hadrons

TL;DR

This paper discusses how the transition time from QCD plasma to hadrons affects the size of the interaction region measured by HBT analyses, estimating a 15% increase in the HBT radius.

Contribution

It highlights the impact of the hadronization transition time on HBT measurements, providing a rough estimate of the resulting increase in interaction region size.

Findings

Transition time increases HBT radius by about 15%

Interaction region size is affected by hadronization dynamics

Implications for interpreting HBT analyses in QCD plasma studies

Abstract

It is pointed out that the size of the interaction region, as determined from HBT analyses, is increased due to the transition time necessary the convert the quarks and gluons into hadrons. A rough estimate yields an increase of R_HBT by about 15%.
