Role of spin-isospin symmetries in nuclear -decays
Simone Salvatore Li Muli, Tor R. Djärv, Christian Forssén +1
A century ago, Wigner's SU(4) symmetry was introduced to explain the properties of atomic nuclei. Despite recent revived interest, its impact on nuclear structure, transitions, and…
Subtractive renormalization of chiral effective theory NN potentials up to next-to-next-to-leading order
C. -J. Yang, Ch. Elster, D. R. Phillips
We have developed a subtractive renormalization method with which we can evaluate nucleon-nucleon (NN) scattering phase shifts produced by the NN potential obtained at leading, nex…
Deuteron Compton Scattering in Chiral Perturbation Theory
M. Malheiro, S. R. Beane, D. R. Phillips +1
Compton scattering on the deuteron is studied in the framework of baryon chiral perturbation theory to third order in small momenta, for photon energies of order the pion mass. The…
Deuteron electromagnetic properties and the viability of effective field theory methods in the two-nucleon system
D. R. Phillips, T. D. Cohen
The central tenet of effective theory is that the details of short-distance physics will not have a significant impact on low-energy observables. Here we perform an analysis of ele…
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…
Regularization and renormalization in effective field theories of the nucleon-nucleon interaction
D. R. Phillips, S. R. Beane, T. D. Cohen
Some form of nonperturbative regularization is necessary if effective field theory treatments of the NN interaction are to yield finite answers. We discuss various regularization s…
The potential of effective field theory in NN scattering
S. R. Beane, T. D. Cohen, D. R. Phillips
We study an effective field theory of interacting nucleons at distances much greater than the pion's Compton wavelength. In this regime the NN potential is conjectured to be the su…
A covariant gauge-invariant three-dimensional description of relativistic bound-states
D. R. Phillips, S. J. Wallace
A formalism is presented which allows covariant three-dimensional bound-state equations to be derived systematically from four-dimensional ones without the use of delta-functions.…
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…
Solving the four-dimensional equations for scalars below meson-production threshold
D. R. Phillips, I. R. Afnan
The four-dimensional equations are adapted to the case of scalar particles with a interaction Lagrangian, and solved for energies below the -production threshold…
Covariant four-dimensional scattering equations for the system
D. R. Phillips, I. R. Afnan
We derive a set of coupled four-dimensional integral equations for the system using our modified version of the Taylor method of classification-of-diagrams. These equation…
The classification of diagrams in perturbation theory
D. R. Phillips, I. R. Afnan
The derivation of scattering equations connecting the amplitudes obtained from diagrammatic expansions is of interest in many branches of physics. One method for deriving such equa…
