Study of the $\rho$ and $\omega$ meson decays into pseudoscalar meson and $e^{+}{e}^{-}$ pair with the CMD-2 detector

2 Collaboration

Using 3.3 pb${}^{-1}$ of data collected with the CMD-2 detector in the 720 -- 840 MeV c.m. energy range, the branching fraction of the conversion decay $\omega \to {\pi }^0{e}^{+}{e}^{-}$ has been measu…
