Heavy quarkonium hybrids from Coulomb gauge QCD
arXiv:0807.2721 · doi:10.1103/PhysRevD.78.056003
Abstract
Using the non-relativisitc reduction of Coulomb gauge QCD we compute spectrum of the low mass hybrid mesons containing a heavy quark-antiquark pair. The gluon degrees of freedom are treated in the mean field approximation calibrated to the gluelump spectrum. We discuss the role of the non-abelian nature of the QCD Coulomb interaction in the ordering of the spin-parity levels.
