概要

• 論文の詳細を見る

• The photodecay width of "ψ" particles into a pseudoscalar meson is theoretically investigated on the basis of the relativistic composite particle model. It is shown that the form factor effect given by this model yields significant reduction for the photodecay width of "ψ", because of large mass difference in the process. By use of broken SU(4) symmetry scheme and the above-mentioned mechanism, the photodecay widths of various vector mesons including "ψ" particles are numerically obtained. These results are in good agreement with the present experimental data.
