【 摘 要 】

We present preliminary results of weak matrix elements relevant to CP violation calculated using the HYP (II) staggered fermions. Since the complete set of matching coefficients at the one-loop level became available recently, we have constructed lattice operators with all the g(sup 2) corrections included. The main results include both (Delta)I = 3/2 and (Delta)I = 1/2 contributions.
