Effective theories of scattering with an attractive inverse-square potential and the three-body problem
Thomas Barford, Michael C. Birse
A distorted-wave version of the renormalisation group is applied to scattering by an inverse-square potential and to three-body systems. In attractive three-body systems, the short…
The Renormalisation Group and Applications in Few-Body Physics
T. Barford
We study the distorted wave renormalisation group (DWRG), a tool for constructing power-counting schemes in systems where some diagrams must be summed to all orders. We solve the D…
An Effective Field Theory for the Three-Body System
T. Barford, M. C. Birse
We study the scattering of a particle from a bound pair in an effective field theory using a distorted-wave renormalisation group method to find the power-counting for the three-bo…
A renormalisation group approach to two-body scattering in the presence of long-range forces
Thomas Barford, Michael C. Birse
We apply renormalisation-group methods to two-body scattering by a combination of known long-range and unknown short-range potentials. We impose a cut-off in the basis of distorted…
A renormalisation-group approach to two-body scattering with long-range forces
Thomas Barford, Michael C. Birse
We apply the renormalisation-group to two-body scattering by a combination of known long-range and unknown short-range forces. A crucial feature is that the low-energy effective th…
