【 摘 要 】

In this work, we perform parameter tuning with dynamical anisotropic clover lattices using the Schrodinger functional and stout-smearing in the fermion field. We find that $/xi(underline)R//xi(underline)0$ is relatively close to 1 in our parameter search, which allows us to fix $/xi(underline)0$ in our runs. We proposed to determine the gauge and fermion anisotropy in a Schrodinger-background small box using Wilson loop ratios and PCAC masses. We demonstrate that these ideas are equivalent to but more efficient than the conventional meson dispersion approach. The spatial and temporal clover coefficients are fixed to the tree-level tadpole-improved clover values, and we demonstrate that they satisfy the nonperturbative condition determined by Schrodinger functional method.
