Abstract
We present results on the B-parameters BK, B3/27 and B3/28, at β=6.0, with the tree-level Clover action. The renormalization of the complete basis of dimension-six four-fermion operators has been performed non-perturbatively. Our results for BK and B3/27 are in reasonable agreement with those obtained with the (unimproved) Wilson action. This is not the case for B3/28. We also discuss some subtleties arising from a recently proposed modified definition of the B-parameters.
