A study of hybrid quarkonium using lattice QCD
arXiv:hep-ph/9711451 · doi:10.1063/1.56000
Abstract
The hybrid quarkonium states are studied using the Born-Oppenheimer expansion. The first step in this expansion is the determination of the energy levels of the gluons in the presence of a static quark-antiquark pair as a function of the quark-antiquark separation. The spectrum of such gluonic excitations is determined from first principles using lattice QCD.
