A Low-Nussinov Model for gamma* p -> V p
I. Royen
Abstract
We show that the lowest-order QCD calculation in a simple model of elastic vector-meson production does reproduce correctly the ratios of cross sections for rho, phi and J/psi (measured by H1 and ZEUS), both in photoproduction and in high-Q2 quasi-elastic scattering. The mass and Q2 dependence of the cross sections is reproduced as well. We also examine the lower-energy data, and see that the energy dependence of the cross section does not depend on Q2, and that a comparison with rho and phi data from NMC suggests a soft pomeron intercept.
