Description

In this paper the problem of the mystery of the σ (700)-meson contribution to the γ, γ → π, π γ, γ → K bar K scattering amplitudes at low energies is studied at the quark level within a soft-pion-constituent-quark diagram technique. The Terent'ev low-energy theorem is derived at the quark level
