Diffractive rho0 photo- and leptoproduction at high energies
Abstract
We discuss the elastic photo- and leptoproduction of rho0-mesons from nucleons at Q2 < 1 GeV2 as studied in recent experiments at HERA and FNAL. We find that the mass distribution of the measured π+π- pairs is determined to a large extent by the two-pion contribution to the photon spectral function as given by the pion form factor. With rising Q2 the rate of diffractive events decreases and the π+π- mass distribution approaches a symmetric shape.
