Improvement and the quenched light hadron spectrum and matrix elements

Abstract We present results for the light hadron spectrum and pseudoscalar decay constant in quenched QCD. Our simulations employ the Wilson gauge action, and the Sheikholeslami-Wohlert fermion action with two choices for the clover coefficient: the tadpole-improved value and the non-pertubatively determined value. Simulations are performed at several lattice spacings to enable extrapolations to the continuum limit.
