Abstract

In this paper we give explicit formulas in momentum and coordinate space for the three-nucleon potentials due to rho and pi meson exchange,derived from off-mass-shell meson-nucleon scattering amplitudes whichare constrained by the symmetries of QCD and by the experimental data. Those potentials have already been applied to nuclear matter calculations. Here we display additional terms which appear to be the most important for nuclear structure. The potentials are decomposed in a way that separates the contributions of different physical mechanisms involved in the meson-nucleon amplitudes. The same type of decomposition is presented for the pi-pi Tucson-Melbourne force: the DELTA isobar, the chiral symmetry breaking, and the nucleon pair terms are isolated.
