Light-cone distribution amplitudes of pseudoscalar mesons from lattice QCD

Abstract We present the first lattice determination of the two lowest Gegenbauer moments of the leading-twist pion and kaon light-cone distribution amplitudes with full control of all errors: a 2 π = 0.101 − 24 + 24 $$ {a}_2^{\pi }={0.101}_{-24}^{+24} $$ for the pion; a 1 K = 0.0533 − 35 + 34 $$ {a}...
