Quark Substructure and Isobar Effects on Deuteron Form-Factors
E. Lomon
Abstract
Elastic ed scattering, with deuteron polarization, up to high momentum transfer provides detailed information on the deuteron wave function. This determines the range dependence of the orbital and spin components of the one- and two-body currents, restricting contributions of isobar and meson-exchange currents and of quark/gluon degrees of freedom, as well as the nucleon component. The R-matrix boundary condition model combines all these effects, predicting nucleon-nucleon reactions and the deuteron form-factors simultaneously. A brief description of the model is followed by a comparison of its results with data, emphasizing the restrictions placed on the model by ed elastic form-factors.
