Meson-nucleon vertex form factors at finite temperature using a soft pion form factor

Abstract

The temperature and density dependence of the meson-nucleon vertex form factors is studied in the framework of thermofield dynamics. Results are obtained for two rather different nucleon-nucleon potentials: the usual Bonn potential and the variation with a softer πNN form factor, due to Holinde and Thomas. In general, the results show only a modest degree of sensitivity to the choice of interaction.
