Gluon Squeezed States in QCD Jet

TL;DR

This paper investigates the formation of gluon squeezed states in nonperturbative QCD jets, analyzing their statistical properties and correlations as a novel quantum phenomenon in high-energy physics.

Contribution

It demonstrates the theoretical possibility of gluon squeezed states in QCD jets and explores their angular and rapidity correlations, a new insight into gluon quantum states.

Findings

Gluon squeezed states can exist in QCD jets

Gluon states exhibit sub- and super-poissonian statistics

Correlation functions depend on angular and rapidity variables

Abstract

We study evolution of colour gluons and prove the possibility of gluon squeezed states at the nonperturbative QCD jet stage. Angular and rapidity dependences of squeezed gluon second correlation function are studied. We demonstrate that the new gluon states can have both sub-poissonian and super-poissonian statistics corresponding to antibunching and bunching of gluons.
