The form factor of the vector meson V conversion transition into the pseudoscalar meson Ρ and the lepton pair l⁺l⁻ is presented for V ≡ ρ⁰, ω, φ and Ρ ≡ π⁰, η. Our approach is based on the chiral effective field theory with resonances. The normalized form factor for ω → πγ* transition was fitted to...
