Charge-symmetry-breaking three-nucleon forces

Leading-order three-nucleon forces that violate isospin symmetry are calculated in heavy-baryon chiral perturbation theory. The effect of the charge-symmetry-breaking three-nucleon force is investigated in the trinucleon systems using Faddeev calculations. We find that the contribution of this force...

Description
Summary:Leading-order three-nucleon forces that violate isospin symmetry are calculated in heavy-baryon chiral perturbation theory. The effect of the charge-symmetry-breaking three-nucleon force is investigated in the trinucleon systems using Faddeev calculations. We find that the contribution of this force to the {sup 3}He-{sup 3}H binding-energy difference is given by {delta}E{sub 3NF}{sup CSB}{approx_equal}5 keV.
