Equivalence of Nonstatic Two-Pion-Exchange Nucleon-Nucleon Potentials

The Nucleon-Nucleon Interaction

Recent developements in our understanding of the fundamental nucleon-nucleon interaction are reviewed. Among the topics considered are (1) the so-called high-precision nucleon-nucleon potentials that emerged in the mid 1990s, (2) progress in the microscopic description of the intermediate-range part of the nucleon-nucleon interaction in terms of correlated pion-pion and rho-pion exchange and (3...

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 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...

Minimally Nonlocal Nucleon-Nucleon Potentials With Chiral Two-Pion Exchange Including Δ Resonances

Ju n 19 97 PERIPHERAL NUCLEON – NUCLEON PHASE SHIFTS AND CHIRAL SYMMETRY ∗

Within the one-loop approximation of baryon chiral perturbation theory we calculate all one-pion and two-pion exchange contributions to the nucleon-nucleon interaction. In fact we construct the elastic NN-scattering amplitude up to and including third order in small momenta. The phase shifts with orbital angular momentum L ≥ 2 and the mixing angles with J ≥ 2 are given parameterfree and thus al...
