Heavy Quark Physics in Nf=2 QCD
CP-PACS Collaboration: S. Aoki et al
Abstract
We present a preliminary analysis of the heavy-heavy spectrum and heavy-light decay constants in full QCD, using a tadpole-improved SW quark action and an RG-improved gauge action on a 16^3 x 32 lattice with four sea quark masses corresponding to m_pi/m_rho = 0.8, 0.75, 0.7, 0.6 and a^-1 = 1.3 GeV. We focus particularly on the effect of sea quarks on these observables.
