Observation of the conversion decay $ϕ\toπ^0e^+e^-$ at CMD-2
Abstract
Description
Using 15.1^{-1} of data collected by CMD-2 in the $ϕ$-meson energy range, the branching ratio of the conversion decay $ϕ\toπ^0e^+e^-$ has been measured for the first time: B(ϕ\toπ^0e^+e^-) = (1.22 \pm 0.34 \pm 0.21) \cdot 10 ^{-5}.
