Masses and decay constants of the light mesons in the quenched approximation using the tadpole--improved SW-clover action

We present results for the masses and decay constants of the light mesons in quenched QCD using the standard gluon action and a tadpole–improved SW–clover fermionic action to reduce discretisation errors. The calculation has been carried out at fixed volume and three lattice spacings corresponding to $\beta =5.7$, $6.0$ and $6.2$. We make comparisons with the conventional SW–clover scheme. We use our results to extract continuum limits and to quantify the size of discretisation errors at smaller $\beta$-values.
