Abstract
We have results from light hadron simulations in quenched QCD at beta=6.0 and 6.2 using non-perturbatively improved Sheikholeslami-Wohlert fermions in an effort to remove all order(a) effects. From looking at hadron masses and splittings and the RG-invariant quark masses (where we have one point at beta=5.7) we suggest this is plausible even with the limited data set. The interpretation of the decay constants appears to be less clear.
