Abstract

We present first results from calculations using an script O sign(a) improved (FNAL) space-time asymmetric fermion action on a 12³ × 24 quenched lattice at β = 5.7 and with csw = 1.57. The mass dependent asymmetry parameter ζ is determined non-perturbatively from the energy-momentum dispersion relation. Calculations have been made in the charm and bottom quark mass sectors in order to test the ζ dependence of the spectrum, since it is at these heavier masses that the asymmetry is expected to be most relevant.
