| Abstract | The spectrum of the Υ system is investigated using the Nonrelativistic Lattice QCD approach to heavy quarks and ignoring light quark vacuum polarization. We find good agreement with experiment for the Υ, Υ, Υ and for the center of mass and fine structure of the χb-states. The lattice calculations predict bb̄ D-states with center of mass at (10.20 ± 0.07 ± 0.03)GeV. Fitting procedures aimed at extracting both ground and excited state energies are developed. We calculate a nonperturbative dispersion mass for the Υ(1S) and compare with tadpole-improved lattice perturbation theory. PACS numbers: 12.38.Gc, 14.40.Gx, 14.65.Fy, 12.39.Hg |
