Numerical study of staggered fermion on anisotropic lattices

Abstract

We study calibration procedures of the staggered quarks on anisotropic lattices in the quenched approximation and in $N_f=2$ dynamical simulations. For the calibration conditions we adopt the hadronic radii $r_0$ and the meson masses in the temporal and spatial directions. On the quenched lattice, we calibrate the quark field and compare the result with the result determined using the meson dispersion relation. In dynamical simulations, we determine the anisotropy parameters ${\gamma }_G$ and ${\gamma }_F$ simultaneously within 1% accuracy at renormalized anisotropy $\xi =a_s/a_t=4$.
