Coulomb Corrections for Coherent Electroproduction of Vector Mesons: Eikonal Approximation
نویسندگان
چکیده
Virtual radiative corrections due to the long range Coulomb forces of heavy nuclei with charge Z may lead to sizeable corrections to the Born cross section usually used for lepton-nucleus scattering processes. An introduction and presentation of the most important issues of the eikonal approximation is given. We present calculations for forward electroproduction of rho mesons in a framework suggested by the VDM (vector dominance model), using the eikonal approximation. It turns out that Coulomb corrections may become relatively large. Some minor errors in the literature are corrected.

Coulomb corrections in quasi-elastic scattering based on the eikonal expansion for electron wave functions
An eikonal expansion is developed in order to provide systematic corrections to the eikonal approximation through order 1/k, where k is the wave number. The expansion is applied to wave functions for the Klein-Gordon equation and for the Dirac equation with a Coulomb potential. Convergence is rapid at energies above about 250 MeV. Analytical results for the eikonal wave functions are obtained f...
متن کاملElectroproduction of Transversely Polarized Vector Mesons Via A Quantum Mechanical Anomaly
By explicit calculation we demonstrate that, in variance with the classical prediction, the leading twist contribution to the exclusive electroproduction of transversely polarized vector mesons from the nucleon does not vanish beyond the leading order in perturbation theory. This appears to be due to a quantum-mechanical anomaly, in the sense that a classical symmetry of the field theory is bro...
متن کاملRadiative Effects in Processes of Diffractive Vector Meson Electroproduction
The electromagnetic radiative correction to the cross section of the vector meson electroproduction is calculated. Explicit covariant formulae for the observed cross section are obtained. The dependence of the radiative correction on the experimental resolution and on the inelasticity cut is discussed. FORTRAN code DIFFRAD based on both exact (ultrarelativistic) and approximate sets of the form...
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...
متن کاملExplicit Proof That Electroproduction of Transversely Polarized Mesons Vanishes in Perturbative Qcd
By means of an explicit one-loop calculation, it is shown that the leading twist contribution to the exclusive electroproduction of transversely polarized vector mesons from the nucleon vanishes. This confirms the all-orders proof by Collins and Diehl. Typeset using REVTEX Permanent Address: Department of Physics, Quaid-e-Azam University, Islamabad 45320, Pakistan
