Extracting the rho meson wavefunction from HERA data

Abstract

We extract the light-cone wavefunctions of the rho meson using the HERA data on diffractive rho photoproduction. We find good agreement with predictions for the distribution amplitude based on QCD sum rules and from the lattice. We also find that the data prefer a transverse wavefunction with enhanced end-point contributions.

13 pages, 7 figures, significant improvements over the original version with a new section on distribution amplitudes added
