摘要：
The problem of the "mystery" of the sigma(700)-meson contribution to the gamma-gamma --> pi-pi and gamma-gamma --> KKBAR 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.
