Hybrid Excitations of the QCD String with Quarks

Abstract

The model for constituent glue is presented starting from the perturbation theory in nonperturbative QCD vacuum. Green function is constructed for a system containing qqbar pair and gluon propagating in the vacuum background field, and Hamiltonian approach to the problem is formulated. The masses of lowest qqbarg hybrids with light quarks are evaluated, and implication of results for the spectroscopy of exotic states is discussed.
