Abstract

At the nonperturbative stage of jet evolution, fluctuations of soft gluons are less than those for coherent states under specific conditions. This fact suggests that there can arise squeezed gluon states. The angular and rapidity dependences of the gluon correlation function are investigated at this stage of jet evolution. It is shown that these new states of soft gluons can display sub-Poissonian or super-Poissonian statistics corresponding to, respectively, antibunching and bunching of gluons, by analogy with squeezed photon states.
