Polarization Observables in Breakup and Quark Degrees of Freedom in the Deuteron
The differential cross section, the tensor analyzing power, , and the
polarization transfer, , in breakup at relativistic
energy are calculated within a model which incorporates multiple scattering and
Pauli principle at quark level. It is shown that the rescattering and quark
exchange affect drastically the polarization observables for kinematical region
corresponding to high internal momentum in the deuteron.Comment: 12 pages, Latex and 4 PostScript figure
Two-component model for the deuteron electromagnetic structure
We suggest a simple phenomenological parametrization for all three deuteron
electromagnetic form factors, and show that a good fit on the available data,
with a minimal number of parameters, can be obtained. The present description
of the deuteron electromagnetic structure is based on two components with
different radii, one corresponding to two nucleons separated by 2 fm,
and a standard isoscalar contribution, saturated by and mesons,
only.Comment: 5 pages, 6 fig. 2 table
