Abstract
We report on our study of two-flavor full QCD on anisotropic lattices using -improved Wilson quarks coupled with an RG-improved glue. The bare gauge and quark anisotropies corresponding to the renormalized anisotropy are determined as functions of and , using the Wilson loop and the meson dispersion relation at several lattice cutoffs and quark masses.
