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 Nf=2N_f = 2 dynamical simulations. For the calibration conditions we adopt the hadronic radii r0r_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 γG\gamma_G and γF\gamma_F simultaneously within 1% accuracy at renormalized anisotropy ξ=as/at=4\xi = a_s/a_t = 4.
