Towards NNLO Accuracy in the QCD Sum Rule for the Kaon Distribution Amplitude

K. G. Chetyrkin, A. Khodjamirian, A. A. Pivovarov

We calculate the $O (α_{s})$ and $O (α_{s}^{2})$ gluon radiative corrections to the QCD sum rule for the first Gegenbauer moment $a_{1}^{K}$ of the kaon light-cone distribution amplitude. The…
