Charm quark contribution to K+ → π+νν at next-to-next-to-leading order

Charm quark contribution to K+ → π+νν at next-to-next-to-leading order

We calculate the complete next-to-next-to-leading (NNLO) order QCD corrections to the charm contribution of the rare decay K+ → π+νν. We present the results for the two-loop matching conditions of the Wilson coefficients, the three-loop anomalous dimensions, and the two-loop matrix elements of the r...
