1 GeV


Generalized Linear Sigma Model Framework:

The two chiral nonets are defined in terms of scalar and pseudoscalarnonets:

At the quark level:

due to the unitarization of

p pscattering amplitude


K-matrix unitarization of prediction for real part of I=J=0 p p scattering amplitue


Summary:

The generalized linear sigma model seems to provide a consistent

picture for the mixing of scalar and pseudoscalar mesons below 2 GeV

Scalar meson content is predicted to be reverse of the pseudoscalar meson

Contant

Future works:

Pi K and pi eta scatterings

Eta prime decays

Inclusion of glueballs
