Abstract

We report on dispersive and finite energy sum rule analyses of the electroweak penguin matrix elements left angle bracket(ππ)2|Q7,8|K0right-pointing angle bracket in the chiral limit. We accomplish the correct perturbative matching (scale and scheme dependence) at NLO in αs, and we describe two different strategies for numerical evaluation.
