The observation of atmospheric neutrinos (See, e.g., Ref.[1]) and solar neutrinos (See, e.g., Ref.[2, 3]) gives the information on the mass squared differences and the mixings, which can be written in the three flavor framework of neutrino oscillations as (|∆m32|, θ23) and (∆m21, θ12), where I have adopted the standard parametrization [4] for the 3× 3 MNSP [5, 6] matrix. On the other hand, the ...

We report on dispersive and finite energy sum rule analyses of the electroweak penguin matrix elements (ππ)2|Q7,8|K 0 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.
