A technique for constructing the nucleon-nucleon transition matrices T in the presence of inelastic channels is given. The present technique avoids the usual potential fit and continues T off the energy shell directly ...

The question of whether one can consistently define and extract nucleon-delta scattering parameters, phase shifts, and inelasticities from the partial-wave NN→NΔ amplitudes is discussed. We have studied the unitarity ...

A Galilean-noninvariant correction to ordinary one-boson-exchange potentials is derived. It gives rise to a three-body force in the three-nucleon system. Its importance for the properties of the three-nucleon bound state ...

Inelastic electron scattering from 3He is studied in the kinematic region of pion production. Inclusive processes with polarization of the electron probe and of the 3He target are described in the plane wave impulse ...

Δ-isobar excitation in the nuclear medium yields an effective three-nucleon force. A coupled-channel formulation of nucleon-deuteron scattering with Δ-isobar excitation developed previously is used. The three-particle ...

The reduction of the two-fermion Bethe-Salpeter equation in the framework of light-front dynamics is studied for the Yukawa model. It yields auxiliary three-dimensional quantities for the transition matrix and the bound ...

Effects on the hadronic and electromagnetic properties of the two-nucleon system above pion threshold, arising from the interaction of the Δ isobar with nucleons, are investigated. The instantaneous nucleon-Δ potential is ...

The description of the three-nucleon system in terms of nucleon and Δ degrees of freedom is extended to allow for explicit pion production (absorption) from single dynamic Δ deexcitation (excitation) processes. This mechanism ...

The interaction between a nucleon and a Δ isobar is studied. The nucleon-Δ potential is derived from a nonrelativistic quark model. It is compared with a corresponding one based on meson exchange. The quark-model potential ...
