Role of relativity and nucleon compositeness in few-body systems
S. J. Wallace
Recent progress is reviewed in four areas where new experimental data have been obtained: proton-proton bremsstrahlung, threshold pion production in proton-proton collisions, elast…
Electron-deuteron scattering in a current-conserving description of relativistic bound states: formalism and impulse approximation calculations
D. R. Phillips, S. J. Wallace, N. K. Devine
The electromagnetic interactions of a relativistic two-body bound state are formulated in three dimensions using an equal-time (ET) formalism. This involves a systematic reduction…
Relativistic three-body bound states and the reduction from four to three dimensions
Paul C. Dulany, S. J. Wallace
Beginning with an effective field theory based upon meson exchange, the Bethe-Salpeter equation for the three-particle propagator (six-point function) is obtained. Using the one-bo…
Low-energy interaction of composite spin-half systems with scalar and vector fields
D. R. Phillips, M. C. Birse, S. J. Wallace
We consider a composite spin-half particle moving in spatially-varying scalar and vector fields. The vector field is assumed to couple to a conserved charge, but no assumption is m…
Relativistic bound-state equations in three dimensions
D. R. Phillips, S. J. Wallace
Firstly, a systematic procedure is derived for obtaining three-dimensional bound-state equations from four-dimensional ones. Unlike ``quasi-potential approaches'' this procedure do…
Instant Two-Body Equation in Breit Frame
N. K. Devine, S. J. Wallace
A quasipotential formalism for elastic scattering from relativistic bound states is based on applying an instant constraint to both initial and final states in the Breit frame. Thi…
