摘要：We present results for the rst two moments of the light-cone distribution amplitudes of the p and
K pseudo-scalar mesons and of the r, K and f vector mesons. The calculations are performed on
the RBC/UKQCD collaborations' ensembles generated with the Iwasaki gauge action and with
2+1 avours of domain wall fermions. In addition we also provide some results on the necessary
non-perturbative renormalisation which we perform using the Rome-Southampton method. We
discuss the benets of the momentum source approach such as much smaller statistical errors and
the possibility to see effects of the discretisation.
