National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Radiative Decays Involving a0(980) and f0(980) in Vector Meson Dominance Model.

DE2005836925

Publication Date	2005
Personal Author	Black, D.; Harada, M.; Schechter, J.
Page Count	12
Abstract	We summarize some features of the vector meson dominance model which was recently proposed for studying radiative decays involving the scalar mesons. Using the experimental values of (Gamma)(a(sub 0) (yields) (gamma)(gamma)), (Gamma)(f(sub 0) (yields) (gamma)(gamma)) and (Gamma)((phi) (yields) a(sub 0) (gamma)) as inputs, we show that the model predicts a large hierarchy between (Gamma)(a(sub 0) (yields) (omega)(gamma)) and (Gamma)(a(sub 0) (yields) (rho)(gamma)) as well as between (Gamma)(f(sub 0) (yields) (omega)(gamma)) and (Gamma)(f(sub 0) (yields) (rho)(gamma)).
