Distribution Amplitudes of Vector Mesons

Presenter: Roger Horsley — University of Edinburgh

R. Horsley (for QCDSF/UKQCD)

Results are presented for low moments of the distribution amplitude for both the ρ and K* vector mesons. Both longitudinal and transverse moments are investigated. We use two flavours of O(a) improved Wilson fermions, together with a non-perturbative renormalisation of the matrix element. Simulations reach down to a pion mass of about 350 MeV.
