Outline of Final Research Achievements

An effective theory of QCD called potential-nonrelativistic QCD (pNRQCD) enables us to investigate various properties of heavy quarkonium by inserting nonperturbative QCD inputs, such as the quark-antiquark potential and its relativistic corrections, computed by lattice QCD simulations. We investigate the mass spectra of quarkonium in pNRQCD using the lattice QCD inputs within the quenched approximation, and develop numerical methods toward accurate determination of the potential including the effect of dynamical quarks. We demonstrate that one of the methods we have found is applicable to compute the three-quark potential accurately.
