Approach for the three-body force effect in a high-energy approximation: Application to hadron-deuteron elastic scattering

Abstract

In the framework of the Glauber approximation, using a simple suggested approach for the three-body force effect and taking into account $D\ensuremath{-}\mathrm{s}\mathrm{t}\mathrm{a}\mathrm{t}\mathrm{e}$ and phase variation effects, $p\ensuremath{-},$ $\overline{p}\ensuremath{-},$ and ${\ensuremath{\pi}}^{\ensuremath{-}}\ensuremath{-}d$ elastic scattering differential cross sections at different energies are calculated. In general, one or two effects only from the three used effects are not enough to obtain a good fit with the data. Thus, with the $D\ensuremath{-}\mathrm{s}\mathrm{t}\mathrm{a}\mathrm{t}\mathrm{e}$ effect as a principal correction, the three-body force effect plays a role in the scattering process. The reality of the three-body force effect with a small contribution can be accepted to obtain a good fit with the experimental data.
