/ Abstract
We present results for the kaon B parameter obtained by APE-100 from a sample of 100 configurations using the Wilson action and 200 configurations using the Clover action, on a 18 3 × 64 lattice at β = 6.0. We have also compared the results for B K using two different values for the effective coupling constant g . We observe a strong dependence of B K on the prescription adopted for g in the Wilson case, contrary to the results of the Clover case which are almost unaffected by the choice of g .
