Renormalisation and power counting in effective field theories for nucleon-nucleon scattering
Keith G. Richardson, Michael C. Birse, Judith A. McGovern
The renormalisation of NN scattering in theories with zero-range interactions is examined using a cut-off regularisation and taking the cut-off to infinity. Inclusion of contact in…
Disoriented chiral condensate formation from tubes of hot quark plasma
Abdellatif Abada, Michael C. Birse
We investigate the time evolution of a system of quarks interacting with sigma and pion fields starting from an initial configuration consisting of a tube of hot quark plasma under…
QCD Sum Rules for the Isospin-Breaking Axial Correlator with Correct Chiral Behavior
Kim Maltman, Michael C. Birse
We revisit the QCD sum-rule treatment of the isospin-breaking axial correlator in light of the recent claim that a previous treatment produced results incompatible with known chira…
Meson properties in an extended nonlocal NJL model
Robert S. Plant, Michael C. Birse
We consider a nonlocal version of the NJL model, based on a separable quark-quark interaction. The interaction is extended to include terms that bind vector and axial-vector mesons…
Relations Among Correlation Functions in the High Temperature Phase of QCD with Broken SU(3)
Michael C. Birse, Thomas D. Cohen, Judith A. McGovern
Group-theoretic arguments are used to determine the dependence of two-point correlators of quark bilinears on the current quark masses. The leading difference between and c…
