Heavy Quarkonia with NRQCD on Symmetric and Asymmetric Lattices from CP-PACS

Abstract: We report on recent results from the CP-PACS Collaboration for the spectrum of heavy quarkonia. Using the NRQCD approach we studied the effect of two dynamical flavours on the spin structure of charmonium and bottomonium for several symmetric lattices. Results are also presented on a quenched study employing coarse and asymmetric lattices to achieve an unprecented control over statistical and systematical errors for higher excited states such as exotic hybrid states.
