A two-component model is developed for diffractive electroproduction of ρ 0 , φ and J/Ψ, based on non-perturbative and perturbative two-gluon exchange. This provides a common kinematical structure for non-perturbative and perturbative effects, and allows the role of the vector-meson vertex functions to be explored independently of the production dynamics. A good global description of the vector-meson data is obtained.

“…The data [13] shows a rapid increase of σ(ψ) from threshold to a local plateau of 25 nb at √ s = 15 GeV. In our interpretation, this is the energy value where the Pomeron contribution is larger than the Reggeon one, safely enabling us to extrapolate to √ s = 180 GeV.…”

The photo-production of J/Ψ-3 He bound state ([ 3 He] J/Ψ ) on a 4 He target has been investigated using the impulse approximation. The calculations have been performed using several γ + N → J/Ψ + N models based on the Pomeron-exchange and accounting for the pion-exchange mechanism at low energies. The J/Ψ wavefunctions in [ 3 He] J/Ψ are generated from various J/Ψ-nucleus potentials which are constructed by either using a procedure based on the Pomeron-quark coupling mechanism or folding a J/Ψ-N potential (v J/Ψ,N ) into the nuclear densities. We consider v J/Ψ,N derived from the effective field theory approach, Lattice QCD, and Pomeron-quark coupling mechanism. The upper bound of the predicted total cross sections is about 0.1 − 0.3 pico-barn. We also consider the possibility of photo-production of a six quark-J/Ψ bound state (
