Note on a sigma model connection with instanton dynamics
Amir H. Fariborz, Renata Jora, Joseph Schechter
It is well known that the instanton approach to QCD generates an effective term which looks like a three flavor determinant of quark bilinears. This has the right behavior to expla…
Scalar Mesons: A Chiral Lagrangian Framework for their Mixing and Substructure
Amir H. Fariborz
The highlights of studies of mixing among scalar mesons below and above 1 GeV within a nonlinear chiral Lagrangian framework is briefly presented. Two scalar meson nonets are intro…
Scalar mesons from an effective Lagrangian approach
Amir H. Fariborz, Renata Jora, Joseph Schechter
A brief discussion of the recent interest in light scalar mesons motivates the study of a generalized linear sigma model. In an SU(3) flavor invariant version of the model there is…
Low energy scattering with a nontrivial pion
Amir H. Fariborz, Renata Jora, Joseph Schechter
An earlier calculation in a generalized linear sigma model showed that the well-known current algebra formula for low energy pion pion scattering held even though the massless Namb…
Two chiral nonet model with massless quarks
Amir H. Fariborz, Renata Jora, Joseph Schechter
We present a detailed study of a linear sigma model containing one chiral nonet transforming under U(1) as a quark-antiquark composite and another chiral nonet transforming as…
