Quenched $SU(3)$ hadron spectroscopy using improved fermionic and gauge actions

Abstract

We present results of quenched $SU(3)$ hadron spectroscopy using $\text{order}(a)$ improved Wilson fermions. The configurations were generated using an $\text{order}(a^2)$ improved 6-link $SU(3)$ pure gauge action at $\beta$'s corresponding to lattice spacings of $0.43$, $0.25$, $0.20$, $0.18$, and $0.15$ fm. We find evidence that fermionic scaling violations are consistent with $\text{order}(a^2)$ errors.
