We present results of a study of BK using tadpole improved gauge-invariant staggered operators. Using three ensembles of 16 3 × 32 configurations with varying numbers of dynamical flavors, we observe a small dependence on N f. Using 7 quenched ensembles at different values of β, we extrapolate to a = 0.
We present our latest results for the ∆I = 1/2 rule, obtained on quenched ensembles with β = 6.0 and 6.2, and a set of N f = 2 configurations with β = 5.7. The statistical noise is quite under control. We observe an enhancement of the ∆I = 1/2 amplitude consistent with experiment, although the systematic errors are still large. We also present a… (More)
