Nonperturbative effects in low energy effective theories of QCD
D. Kalafatis
In this talk I concentrate on the role of chiral symmetry realisation by spin-1 fields in the low energy QCD effective lagrangian. I assume that chiral symmetry is nonlinearly real…
Towards a unified theory of mesons and baryons
Dimitri Kalafatis
In this review we report on advances in topological soliton models of the nucleon. In chapter I we construct an effective lagrangian of QCD with the low mass mesons ( and…
Constraints on Four-Point Couplings in Low-Energy Meson Interactions
D. Kalafatis, M. C. Birse
We investigate from first principles the introduction of isospin-1 vector and axial-vector fields into the nonlinear sigma model. Chiral symmetry is nonlinearly realised and spin-1…
On the role of vector mesons in topological soliton stability
A. Abada, D. Kalafatis, B. Moussallam
Isospin one vector mesons (in particular the ) are usually described as massive Yang-Mills particles in the chiral Lagrangian. We investigate some aspects of an alternative appr…
