{pi}{rho} correlations in the {ital NN} potential
- Institut fuer Kernphysik, Forschungszentrum Juelich GmbH, D-52425 Juelich (Germany)
We evaluate the contribution to the nucleon-nucleon interaction due to correlated {pi}{rho} exchange in the {pi}, {omega}, and {ital A}{sub 1}/{ital H}{sub 1} channels by means of dispersion-theoretic methods based on a realistic meson-exchange model for the interaction between {pi} and {rho} mesons. This process has substantial effects: In the pionic channel it counterbalances the suppression generated by a soft {pi}{ital NN} form factor of monopole type with a cutoff mass of about 1 GeV; in the {omega} channel it provides a strong repulsive contribution, leaving little room for explicit quark-gluon effects. {copyright} {ital 1996 The American Physical Society.}
