Addendum to: Light-cone distribution amplitudes of pseudoscalar mesons from lattice QCD

Abstract

We update our lattice determination of the two lowest Gegenbauer moments
of the leading-twist pion and kaon light-cone distribution amplitudes [1] using the recently
calculated three-loop matching factors for the conversion from the RI0/SMOM to the MS
scheme [2, 3]. We find a�2 = 0.116+19
−20 for the pion, aK1
= 0.0525+31
−33 and aK2
= 0.106+15
−16 for
the kaon. Updated plots can be found in the appendix in the arXiv submission.
