Quartet n-d scattering lengths are calculated using second-generation nucleon-nucleon potential models. These results are compared to the corresponding quantity recently calculated using chiral perturbation theory. 1 Accurate calculations of n-d quartet scattering lengths were first performed 10 years ago[1]. This quantity is known to be insensitive to most physics, such as ℓ > 0 partial waves ...

A model calculation of nucleon-nucleon scattering is presented, which results in an amplitude that in the elastic high energy limit realizes the Wu-Yang idea regarding the relation between the elastic form factor of the nucleon and the differential cross section; and which is consistent with the behavior of the differential cross section for the production of nucleon resonances. The calculation...

We report on recent progress achieved in calculating various few–nucleon low–energy observables from effective field theory. Our discussion includes scattering and bound states in the 2N, 3N and 4N systems and isospin violating effects in the 2N system. We also establish a link between the nucleon–nucleon potential derived in chiral effective field theory and various modern high–precision poten...

We use non-relativistic dynamics to relate the deuteron form factor at high momentum transfer to the high energy neutron-proton scattering amplitude. This relation implies that an accurate computation of the form factors at large Q2 requires a simultaneous description of the lowest phase-shifts of the nucleon-nucleon elastic scattering at laboratory kinetic energy T ∼ Q/2mN . Computing these ph...

Glauber theory for nucleus-nucleus scattering at high incident energies is reformulated so as to become applicable also for the scattering at intermediate energies. We test validity of the eikonal and adiabatic approximations used in the formulation, and discuss the relation between the present theory and the conventional Glauber calculations with either the empirical nucleon-nucleon profile fu...
