Medium modifications of the intermediate range in the NN potential

Based on a realistic model for the N N → ππ helicity amplitudes, we study medium modifications of the σ channel in the NN potential. These modifications arise from a change in the ππ rescattering through the in-matter pion dispersion relation. We also consider the possibility of dropping meson masse...

Description
Summary:Based on a realistic model for the N N → ππ helicity amplitudes, we study medium modifications of the σ channel in the NN potential. These modifications arise from a change in the ππ rescattering through the in-matter pion dispersion relation. We also consider the possibility of dropping meson masses as suggested by QCD sum rules.
