Meson Octet

We present details of a model for calculating the mass spectrum of light-quark mesons and decay constants of the pseudoscalar meson octet from a phenomenological model based on Dyson–Schwinger and Bethe–Salpeter equations. In this model the Bethe-Salpeter kernel is approximated by a separable ansatz obtained from input quark propagators.

Meson Octet

The effective Lagrangian for pseudoscalar meson octet including terms up to fourth order in momenta and masses is derived from a linear sigma model with vector and axial mesons. The mass of scalar meson nonet 720±75 MeV ensures a good fit of coefficients in effective Lagrangian with values derived from experiment.

Meson Octet

We investigate the chiral log corrections to the electromagnetic self-energies of the pseudoscalar meson octet and demonstrate that, for the charged pions and kaons, such corrections, at scales μ ~ 1 GeV , are large. We argue that this indicates that leading order chiral results may be misleading in the electromagnetic sector and discuss information on η → 3π and isospin breaking in Kl3 which support this interpretation.
