CORRELATION SIGNS OF INSTANTONS AND SQUEEZED GLUON STATES IN HEP PROCESSES

摘要

Correlation features of two new nonperturbative phenomena: instantons and gluon squeezed states are discussed as the objects for experimental search at HERA and LEP. Second correlation function for multiple gluon production in the field of classical instanton with the first quantum correction is calculated in QCD. The features of the gluon correlations can be used as a signal of instanton at HERA experiment. Quantum nonperturbative colour gluon squeezed states can lead to specific correlations in dependence on jet variables. Condition of squeezing is checked and second correlation function is obtained for different subjet structures.
