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…

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…
