Abstract [en]

The decays of narrow light vector mesons into pseudoscalar mesons and dileptons are calculated to leading order in a recently proposed scheme which treats pseudoscalar and vector mesons on equal footing. Since all required parameters have been determined by other reactions the presented approach gains predictive power for the considered processes. The decay of the omega-meson into pion and dimuon agrees reasonably well with the available experimental data concerning form factor, single-differential decay width and partial decay width. As well do the partial decay width of the w-meson into a pion and a dielectron and of the phi-meson into an eta-meson and a dielectron. The decay properties of the omega-meson into eta-meson and dimuon or dielectron and of the phi-meson into eta-meson and dimuon are predicted.
