Vector Meson Photoproduction in the Soft Dipole Pomeron Model Framework
نویسنده
چکیده
Exclusive photoproduction of all vector mesons by real and virtual photons is considered in the Soft Dipole Pomeron model. It is emphasized that being the Pomeron in this model a double Regge pole with intercept equal to one, we are led to rising cross-sections but the unitarity bounds are not violated. It is shown that all available data for ρ, ω, φ, J/ψ and Υ in the region of energies 1.7 ≤W ≤ 250 GeV and photon virtualities 0 ≤ Q2 ≤ 35 GeV2 , including the differential cross-sections in the region of transfer momenta 0 ≤ |t| ≤ 1.6 GeV2, are well described by the model.

Regge pole model for all vector meson exclusive photoproduction by real and virtual photons
A model based on a dipole Pomeron framework for vector meson exclusive photoproduction by real and virtual photons shows very good agreement with the experimental data. The model does not violate unitarity constrains and describes in a universal manner all the available data for ρ, ω, ϕ, J/ψ and Υ vector meson photoproduction in the region of energies 1.7 ≤ W ≤ 250 GeV and photon virtualities 0...

We calculate the nuclear cross section for vector meson exclusive photoproduction within the QCD color dipole picture and in the Regge approach. For the first one, we have considered the phenomenological saturation model, whereas for the latter we use a model based on the dipole Pomeron framework. Theoretical estimates for both light and heavy nuclei are given over a large range of energies.

متن کاملDiffractive Vector Meson Photoproduction from Dual String Theory
We study diffractive vector meson photoproduction using string theory via AdS/CFT. The large s behavior of the cross sections for the scattering of the vector meson V on a proton is dominated by the soft Pomeron, σV ∼ s2ǫ−2α′P/B, where from the string theory model of [9], ǫ is approximately 1/7 below 10 GeV, and 1/11 for higher, but still sub-Froissart, energies. This is due to the production o...
