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…
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…
Comment on "Suppression of piNN* Coupling and Chiral Symmetry"
Michael C. Birse
Jido, Oka and Hosaka have shown that the p-slash gamma_5 piece of the pion-to-vacuum correlator of two baryon interpolating fields vanishes in the soft-pion limit, as a consequence…
