Chiral effective field theory of Delta(1232) and Compton scattering
V. Pascalutsa, D. R. Phillips
A new power-counting scheme for a chiral effective field theory that includes Delta degrees of freedom is briefly described and applied to the nucleon Compton scattering.
Electron-deuteron scattering in a current-conserving description of relativistic bound states: including meson-exchange-current contributions
D. R. Phillips, S. J. Wallace, N. K. Devine
Using a three-dimensional formalism that includes relativistic kinematics, the effects of negative-energy states, approximate boosts of the two-body system, and current conservatio…
Electron-deuteron scattering in a relativistic theory of hadrons
Daniel R. Phillips
We review a three-dimensional formalism that provides a systematic way to include relativistic effects including relativistic kinematics, the effects of negative-energy states, and…
Regularization and the potential of effective field theory in nucleon-nucleon scattering
D. R. Phillips
This paper examines the role that regularization plays in the definition of the potential used in effective field theory (EFT) treatments of the nucleon-nucleon interaction. I cons…
Perturbation schemes for systems of nucleons and pions: The relationship of covariant perturbation theory, the convolution integral and time-ordered perturbation theory
D. R. Phillips, I. R. Afnan
This paper is the first in a series of three which attempt to resolve the difficulties that have plagued the problem for the past ten years. Various theoretical inconsiste…
