New approach to a global description of the deuteron electromagnetic structure

Technical Report:

Abstract

A new approach to a global description of the deuteron electro-magnetic (EM) structure is developed on the bases of a modification of the well known vector-meson-dominance (VMD) model of EM hadron interactions by incorporating the true deuteron form factor (FF) analytic properties, non-zero vector meson widths and the correct power asymptotic behaviour as predicted by QCD. As a result, the experimental data on elastic electron-deuteron scattering structure functions A(t) and B(t) are described quite well, the deuteron EM FF`s in the space-like region are reproduced and their behaviour in the time- like region is predicted. At the same time the couplings of the {omega}-mesons to deuteron are evaluated and the total cross section of e{sup +}e{sup -} {yields} dd-bar process is determined for the first time.
