Parton distribution amplitudes and non-perturbative renormalisation
Parton distribution amplitudes and non-perturbative renormalisation
We present results for the first two moments of the light-cone distribution
amplitudes of the pion and kaon pseudo-scalar mesons and of the rho, K* and phi
vector mesons. The calculations are performed on the RBC/UKQCD collaborations'
ensembles generated with the Iwasaki gauge action and with 2+1 flavours 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 benefits of the momentum source approach such as much
smaller statistical errors and the possibility to see effects of the
discretisation.

Abstract
We present results for the first two moments of the light-cone distribution
amplitudes of the pion and kaon pseudo-scalar mesons and of the rho, K* and phi
vector mesons. The calculations are performed on the RBC/UKQCD collaborations'
ensembles generated with the Iwasaki gauge action and with 2+1 flavours 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 benefits of the momentum source approach such as much
smaller statistical errors and the possibility to see effects of the
discretisation.
