On the Nf and a dependence of BK

We present results of a study of B K 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...

Description
Summary:We present results of a study of B K 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.
