Born-Oppenheimer potentials for S U ( 3 ) gauge theory
Year: 2024
Type: article
Abstract: We develop parametrizations of eight of the lowest Born-Oppenheimer potentials for quarkonium hybrid mesons as functions of the separation r of the static quark and antiquark sources. The parameters are determined by fitting results calculated using pure S U ( 3 ) lattice gauge theory. The parametrizations have the correct limiting behavior at small r , where the potentials form multiplets associated with gluelumps. They have the correct limiting behavior at large r , where the potentials form multiplets associated with excitations of a relativistic string. There is a narrow avoided crossing in the small- r region between two potentials with the same Born-Oppenheimer quantum numbers. Published by the American Physical Society 2024
