Light-Cone Distribution Amplitudes
Presenter: Christopher Sachrajda — University of Southampton
We present results for the first two moments of the light-cone distribution amplitudes of the π and K pseudoscalar mesons and of the ρ K∗ and φ vector mesons. Results for the couplings of the vector mesons to the vector and tensor currents are also presented. The measurements were performed on the UKQCD/RBC collabotations' Domain Wall Fermion configurations with the Iwasaki gauge action at a lattice spacing of a−1≃ 1.6 GeV. The phenomenological significance of the results is also briefly reviewed.
