Nucleon–nucleon and Pion–nucleon Potentials from Phase Shifts Using Quantum Inversion
NN and πN partial wave radial potentials have been generated using the latest SM94–VPI(NN) and FA93–VPI(πN) phase shifts. The potentials are used to determine the deuteron properties and to compute the H and He binding energies. The ε1 mixing angles of SM94–VPI and NY93–Nijmegen differ significantly and inversion potentials yield a Pd of 6.37% and 5.78%, respectively. Under–binding of H and He ...
متن کاملParity-violating two-pion exchange nucleon-nucleon interaction
We calculate in chiral perturbation theory the parity-violating two-pion exchange nucleon-nucleon potentials at leading one-loop order. At a distance of r = m−1 π ≃ 1.4 fm they amount to about ±16% of the parity-violating 1π-exchange potential. We evaluate also the parity-violating effects arising from 2π-exchange with excitation of virtual ∆(1232)-isobars. These come out to be relatively small...
متن کاملThe 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...
متن کاملThe nucleon - nucleon interaction
We review the major progress of the past decade concerning our understanding of the nucleon-nucleon interaction. The focus is on the low-energy region (below pion production threshold), but a brief outlook towards higher energies is also given. The items discussed include charge-dependence, the precise value of the πN N coupling constant, phase shift analysis and high-precision NN data and pote...
متن کاملNucleon and Pion-nucleon Form Factors from Lattice Qcd
The isovector Nucleon electromagnetic form factors GE(q ) and GM(q ) are evaluated in Lattice QCD using Wilson fermions. A lattice of spatial extent 3 fm is used in the quenched theory allowing the extraction of the form factors for momentum transfer squared between 0.1 and 2 GeV for lowest pion mass of about 400 MeV. The calculation is also performed using two degenerate dynamical flavors of W...
