Abstract

We introduce new values of the strength constants (i.e., a, b, c, and d coefficients) of the Tucson-Melbourne (TM) 2π exchange three nucleon potential. The new values come from contemporary dispersion relation analyses of meson factory πN scattering data. We make variational Monte Carlo calculations of the triton with the original and updated three-body forces to study the effects of this update. We remove a short-range -- π-range part of the potential due to the c coefficient and discuss the effect on the triton binding energy.
