Scheming in Dimensional Regularization
D. R. Phillips, S. R. Beane, M. C. Birse
We consider the most general loop integral that appears in non-relativistic effective field theories with no light particles. The divergences of this integral are in correspondence…
The Wilson Renormalisation Group Applied to the Potential in NN Scattering
Michael C. Birse, Judith A. McGovern, Keith G. Richardson
Nonrelativistic two-body scattering by a short-ranged potential is studied using the renormalisation group. Two fixed points are identified: a trivial one and one describing system…
On the absence of fifth-order contributions to the nucleon mass in heavy-baryon chiral perturbation theory
Judith A. McGovern, Michael C. Birse
(New version with some expanded discussion; figures and minor typos corrected.) We have calculated the contribution proportional to the fifth power of the pion mass in the chiral e…
A renormalisation-group treatment of two-body scattering
Michael C. Birse, Judith A. McGovern, Keith G. Richardson
Nonrelativistic two-body scattering by a short-ranged potential is studied using the renormalisation group. Two fixed points are identified: a trivial one and one describing system…
Chiral symmetry in matter
Michael C. Birse
Soft-pion theorems are used to show how chiral symmetry constrains the contributions of low-momentum pions to the quark condensate, the pion decay constant and hadron masses, all o…
Renormalising NN scattering: is power counting powerless?
Michael C. Birse
The renormalisation of NN scattering in theories with zero-range interactions is examined using a cut-off regularisation where the cut-off is taken to infinity, dimensional regular…
