The static quark potential in full QCD

Abstract

We report results on the static quark potential in two-flavor full QCD. The calculation is performed for three values of lattice spacing $a^{-1}\approx 0.9,1.3$ and 2.5 GeV on $12^3\times 24,16^3\times 32$ and $24^3\times 48$ lattices respectively, at sea quark masses corresponding to $m_{\pi }/m_{\rho }\approx 0.8-0.6$. An RG-improved gauge action and a tadpole-improved SW clover quark action are employed. We discuss scaling of $m_{\rho }/\sqrt{\sigma }$ and effects of dynamical quarks on the potential.
