摘要：

One-loop corrections to the fermion rest mass M-1, wave function renormalization Z(2) and speed of light renormalization C-0 are presented for lattice actions that combine improved glue with clover or D234 quark actions and keep the temporal and spatial lattice spacings, a(t) and a(s), distinct. We explore a range of values for the anisotropy parameter chi = a(s)/a(t) and treat both massive and massless fermions.
