Are back-to-back particle--antiparticle correlations observable in high energy nuclear collisions?

TL;DR

This paper provides analytical estimates indicating that the finite duration of transition dynamics in high energy nuclear collisions likely suppresses observable back-to-back particle-antiparticle correlations.

Contribution

It introduces analytical formulae to quantify the suppression of back-to-back correlations caused by finite transition durations.

Findings

Suppression of correlations due to finite transition time.

Unlikelihood of observing the effect in experiments.

Abstract

Analytical formulae are presented which provide quantitative estimates for the suppression of the anticipated back-to-back particle--antiparticle correlations in high energy nuclear collisions due to the finite duration of the transition dynamics. They show that it is unlikely to observ the effect.
