Precision [Upsilon] spectroscopy from nonrelativistic lattice QCD

The spectrum of the [Upsilon] 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 [Upsilon],[Upsilon][prime],[Upsilon][prime][prime] and for the center of mass and fine structure of the [chi][sub [ital b]] states. The lattice calculations predict [ital b[bar b]] [ital D] states with a center of mass at (10.20[plus minus]0.07[plus minus]0.03) GeV. Fitting procedures aimed at extracting both ground and excited state energies are developed. We calculate a nonperturbative dispersion mass for the [Upsilon](1[ital S]) and compare it with tadpole-improved lattice perturbation theory.

Bc spectroscopy from lattice QCD

Abstract We present first results for B c spectroscopy using Lattice QCD. We use a non-relativistic effective action, matched to full QCD, which includes spin-independent relativistic corrections. This approach represents a considerable step beyond the potential models previously available. We use multi-exponential fits to multiple correlation functions to extract ground and excited S states and give accurate values for the S state hyperfine splitting and the P state ( B c ∗∗ ) fine structure, including the effects of 1 P 1 3 P 1 mixing.We present first results for
