Ground State Energies

Three-nucleon systems are considered assuming the neutrons and protons to be distinguishable particles. The configuration space Faddeev equations are exploited to calculate ground state energies of 3H and 3He nuclei within an [Formula: see text]-wave approach applying the Malfliet–Tjon, Tamagaki G3RS and Afnan–Tang ATS3 NN potentials. We modify the potentials by scaling strength parameters to define [Formula: see text], [Formula: see text] and [Formula: see text] singlet components. The scaling parameters are fixed to reproduce experimental scattering lengths. The charge symmetry breaking energy is numerically evaluated. The relation between [Formula: see text], [Formula: see text] and [Formula: see text] singlet potentials is discussed.

Simple Quark Model

In generating a charge-symmetry breaking potential using ρ-ω mixing it is usually assumed that the mixing amplitude is constant (at the on-mass-shell value). Since the exchanged meson is actually far off-shell one must question the validity of this assumption. By constructing a simple quark model in which the mixing is generated by the u-d quark mass difference, we find that the assumption seems to be a very poor one.
