Study of Scalar Mesons and Related Radiative Decays

摘要

After a brief review of the puzzling light scalar meson sector of QCD, a brief summary will be given of a paper concerning radiative decays involving the light scalars. There, a simple vector meson dominance model is constructed in an initial attempt to relate a large number of the radiative decays involving a putative scalar nonet to each other. As an application it is illustrated why a(sub 0)(980)-f(sub 0)(980) mixing is not expected to greatly alter the f(sub 0)/a(sub 0) production ratio for radiative(phi) decays.
