A phenomenological Lorentz covariant representation of the NN t-matrix has been obtained with parameters that are explicitly energy dependent. The real and imaginary parts of the t …
A Lorentz invariant form of the NN amplitude is fit with a simple model which includes direct and exchange first Born terms from a number of ''mesons.''The (complex) couplings and …
A Lorentz-invariant representation for NN scattering amplitudes is derived. The general NN representation assuming parity invariance involves 128 amplitudes for a given isospin, all …
Previous work on the general representation of NN scattering amplitudes in the full Dirac space of two nucleons is extended to allow a simple realization of the generalized Pauli …
For laboratory kinetic energies between 50 and 200 MeV, we focus on generating an energy- dependent Lorentz covariant parametrization of the on-shell nucleon-nucleon (NN) …

Within the framework of the relativistic plane wave impulse approximation (RPWIA), complete sets of quasielastic (p→, p′) and (p→, n→) spin observables are calculated …
A density-dependent effective interaction is derived from a complete set of Lorentz-invariant NN amplitudes. Its use in a Schrödinger formalism produces results equivalent to use of the …
We investigate the difference between those relativistic models based on interpreting a realistic nucleon-nucleon interaction as a perturbation of the square of a relativistic mass …
Relativistic density-dependent effective interactions for nucleon-nucleus scattering based upon a complete set of Lorentz-invariant NN amplitudes are used in calculations of elastic …
