### Electroweak penguin contributions to non-leptonic δf = 1 decays at NNLO

Abstract:

We calculate the θ(αs) corrections to the Z°-penguin and electroweak box diagrams relevant for non-leptonic ΔF = 1 decays with F = S,B. This calculation provides the complete O(αwαs) and θ(αwαssin2θwm2t) corrections (αw = α/sin2θw) to the Wilson coefficients of the electroweak penguin four quark operators relevant for non-leptonic K- and B-decays. We argue that this is the dominant part of the next-next-to-leading (NNLO) contributions to these coefficients. Our results allow us to reduce cons...
