Squeezed States of Colour Gluons in QCD Isolated Jet.
V.I. Kuvshinov and V.A. Shaparau

We study evolution of colour gluon states in isolated QCD jet and prove the possibility of existence of the gluon squeezed states at the nonperturbative stage of the jet evolution. Angular and rapidity dependencies of gluon squeezed second correlation function are studied. We demonstrate that these new gluon states can
have both sub-Poissonian and super-Poissonian statistics corresponding to antibunching and bunching of gluons.
Key words: squeezed states, nonperturbative stage, QCD jet, correlation function.
