  • 摘要:In this work, we perform parameter tuning with dynamical anisotropic clover lattices using the Schrödinger functional and stout-smearing in the fermion eld. We nd that xR=x0 is relatively close to 1 in our parameter search, which allows us to x x0 in our runs. We proposed to determine the gauge and fermion anisotropy in a Schrödinger-background small box using Wilson loop ratios and PCAC masses. We demonstrate that these ideas are equivalent to but more efcient than the conventional meson dispersion approach. The spatial and temporal clover coefcients are xed to the tree-level tadpole-improved clover values, and we demonstrate that they satisfy the nonperturbative condition determined by Schrödinger functional method.
