Coherence Effects in Diffractive Electroproduction of ρ Mesons from Nuclei
نویسندگان
چکیده
A systematic multiple scattering formalism for vector meson electroproduction from nuclei is developed, with emphasis on the formation, propagation and hadronization scales for quark-gluon fluctuations of the virtual high-energy photon. The theory is compared to HERMES measurements of ρ electroproduction on 14 N. The nuclear transparency as a function of the vector meson propagation length is well reproduced .

Coherence Effects in Diffractive Electroproduction from Nuclei
We argue that study of the cross section of coherent photo(electro) production of ρ, ρ, ...-mesons provides an effective method to probe onset of black body limit(BBL) in the soft and hard QCD interactions. We illustrate the expected features of the onset of BBL using generalized vector dominance model(GVDM). We show that this model describes very well ρ-meson coherent photoproduction at 6 ≤ Eγ...
متن کاملDiffractive electroproduction of ρ meson excitations
We use perturbative QCD and parton-hadron duality to estimate the cross sections for the diffractive electroproduction of ρ ′ (1 −) and ρ(3 −) resonances which occur in the 1.3– 1.8 GeV mass interval. We present the cross sections and the ratios σ L /σ T as a function of Q 2. We compare the predictions with those for the diffractive electroproduction of ρ mesons. We show how such diffractive el...
متن کاملColor Transparency at Low Energies: Predictions for JLAB
The study of color transparency (CT) in elastic electroproduction of vector mesons off nuclei encounters the problem of the onset of coherence length (CL) effects. The problem of CT-CL separation arises especially at medium energies, corresponding to HERMES experiment, when the coherence length is of the order of the nuclear radius RA. Only at asymptotic large energies, corresponding to large C...
متن کاملDiffractive Ρ Meson Electroproduction at High Q 2 and High |t|
The electroproduction of ρ mesons is studied at HERA with the H1 detector at high Q and high |t|. Cross sections are measured as a function of Q, W and t. The W dependence of the γ∗p cross section is observed to increase with Q from values compatible with soft Pomeron exchange at low Q to a hard dependence at large Q. Spin density matrix elements are measured and their dependence is compared wi...
متن کاملA-dependence of coherent electroproduction of ρ mesons on nuclei in forward direction
This article presents the A-dependence of the differential cross section for the coherent electroproduction of vector mesons on nuclei in forward direction, at fixed values of longitudinal momentum transfer qL. It is shown that such cross section has complicated behavior over the atomic mass number A with local minimums and maximums. It is also shown that a ratio of the real to the imaginary pa...
