[en] A method to determine masses, widths and coupling constants of vector mesons, like φ(1020), ω(782) and ρ⁰(770) recurrences is defined. Starting from data on decay rates and cross-sections for the processes: φ→M_Iγ, φ→M_Ie⁺e^- and e⁺e^-→M_Iφ, where M_I is a pseudoscalar or scalar meson with isospin I=0,1, the time-like transition form factors, which describe the vertex φγM_I, are parameterized using a vector-meson-propagators description in the low-energy region (<3-4 GeV), the quark-counting rule prescription for the high-energy behavior, and the analyticity imposed by means of the dispersion relations.
