Abstract

We study the hadronic spectrum in quenched lattice QCD using an improved Wilson fermion action (Hamber-Wu(1983),Eguchi-Kawamoto(1984)) at $\beta= 5.7$ and $\beta =6.0$ . We find a systematic reduction of the finite spacing effects compared to the results obtained by using the standard Wilson action.
