On radiative widths and a pattern of quark-diquark-gluon configuration mixing in low-lying scalar mesons

High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

The earlier suggested and developed idea of quark-hadron duality, underlying "bremsstrahlung-weighted" sum rules for total or polarized photon interaction cross sections, is applied to the description of excitation of light scalar mesons in gamma-gamma interactions. The emphasis is put on the discussion of a role of the scalar diquark cluster degrees of freedom in the radiative formation of light scalar mesons.
