Helicity in diffractive vector-meson production
I. Royen
We study the helicity amplitudes describing the quasielastic production of vector mesons in deep inelastic scattering within the context of the model which we previously introduced…
The Transverse Cross Section in Exclusive Vector-Meson Production
J. R. Cudell, I. Royen
We show that the ratio of the transverse to the longitudinal cross sections observed at HERA cannot be reproduced by models which assume that the meson can be described by an on-sh…
A Low-Nussinov Model for Elastic Vector Meson Production at HERA
I. Royen
I show that a lowest-order pQCD calculation of elastic vector-meson production does reproduce all the features of experimental measurements at HERA, for all Q^2 and all mesons, at…
A Low-Nussinov Model for gamma* p -> V p
I. Royen
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 (mea…
