Isospin symmetry breaking nucleon-nucleon potentials and nuclear structure
نویسندگان
چکیده
Modern nucleon-nucleon (NN) potentials, which accurately fit the nucleon-nucleon scattering phase shifts, contain terms which break isospin symmetry. The effects of these symmetry violating terms on the bulk properties of nuclear matter are investigated. The predictions of the charge symmetry breaking (CSB) terms are compared with the Nolen-Schiffer (NS) anomaly regarding the energies of neighboring mirror nuclei. We find that, for a quantitative explanation of the NS anomaly, it is crucial to include CSB in partial waves with L > 0 (besides S0) as derived from a microscopic model for CSB of the NN interaction.

Dominant 2πγ-exchange nucleon-nucleon interaction: Spin-spin and tensor potentials
We calculate at two-loop order in chiral perturbation theory the electromagnetic corrections to the two-pion exchange nucleon-nucleon interaction that is generated by the isovector spin-flip ππNN contact-vertex proportional to the large low-energy constant c4 ≃ 3.4GeV−1. We find that the respective 2πγ-exchange potentials contain sizeable isospinbreaking components which reach up to −4% of corr...

We compute isospin-violating meson-nucleon coupling constants and their consequent charge-symmetry-breaking nucleon-nucleon potentials. The couplings result from evaluating matrix elements of quark currents between nucleon states in a nonrelativistic constituent quark model; the isospin violations arise from the difference in the up and down constituent quark masses. We find, in particular, tha...

We calculate at two-loop order in chiral perturbation theory the electromagnetic corrections to the dominant two-pion exchange nucleon-nucleon interaction that is generated by the isoscalar πN contact-vertex proportional to the large low-energy constant c 3. We find that the respective 2πγ-exchange potential contains sizeable isospin-breaking components which amount to about −1% of the strongly...
متن کامل- nucleon interactions and charge - symmetry breaking in nuclei
Coulomb displacement energies, i.e., the differences between the energies of corresponding nuclear states in mirror nuclei, are evaluated using recent models for the nucleon-nucleon (NN) interaction. These modern NN potentials account for breaking of isospin symmetry and reproduce pp and pn phase shifts accurately. The predictions by these new potentials for the binding of 16O are calculated. A...
متن کاملThe Nucleon-Mass Difference in Chiral Perturbation Theory and Nuclear Forces
A new method is developed for treating the effect of the neutron-proton mass difference in isospin-violating nuclear forces. Previous treatments utilized an awkward subtraction scheme to generate these forces. A field redefinition is used to remove that mass difference from the Lagrangian (and hence from asymptotic nucleon states) and replace its effect by effective interactions. Previous calcu...
