Lattice results for low moments of light meson distribution amplitudes

As part of the UKQCD and RBC collaborations’ Nf=2+1 domain-wall fermion phenomenology programme, we calculate the first two moments of the light-cone distribution amplitudes of the pseudoscalar mesons ? and K and the (longitudinally polarized) vector mesons ?, K*, and ?. We obtain the desired quantities with good precision and are able to discern the expected quark-mass dependence of SU(3)-flavor breaking effects. An important ingredient of the calculation is the nonperturbative renormalization of lattice operators using a regularization-independent momentum scheme
