Rare decay K+ →π+ ν ν̄ at the next-to-next-to-leading order m QCD

We calculate the charm quark contribution to the rare decay K+ →π+ ν ν̄ in the next-to-next-to-leading order of QCD. This new contribution reduces the theoretical uncertainty in the relevant parameter P c from ± 10.1% down to ± 2.4%, corresponding to scale uncertainties of ± 1.3%, ± 1.0%, ± 0.006, a...
