Hybrid mesons with heavy quarks

Abstract

Abstract Model-independent features of hybrid meson states are discussed. These general arguments are applied to the QCD-based constituent gluon model based on the Vacuum Background Correlators Method (VBCM). The leading-order Hamiltonian is derived from the general formalism.The masses of heavy quark hybrids, including charmonium hybrid states, are calculated. We predict ccg hybrids at 4·1 ± 0·1 GeV and bbg ones at 10·5 ± 0·1 GeV. Comparison with some other models are made.
