abstract = {We present a study of the rare charm meson decays $
D^{0}\rightarrow K^{+}K^{-}e^{+}e^{-} $, $
π^{+}π^{-}e^{+}e^{-} $, and $ K^{-}π^{+}e^{+}e^{-} $
using a 942 fb$^{-1}$ data set collected by the Belle
detector at the KEKB asymmetric-energy $ e^{+}e^{-} $
collider. We use $ D^{0} $ candidates identified by the
charge of the pion in $ D^{*} \rightarrow D^{0} π$ decays
and normalize the branching fractions to $ D^{0} \rightarrow
K^{-}π^{+}π^{-}π^{+} $ decays. The branching fraction for
decay $ D^{0} \rightarrow K^{-}π^{+}e^{+}e^{-} $ is
measured to be (39.6 $\pm$ 4.5 (stat) $\pm$ 2.9 (syst))
$\times$ $10^{-7}$, with the dielectron mass in the $ ρ/ω$
mass region $ 675 < m_{ee} < 875 $ MeV$/c^{2}$. We also
search for $ D^{0}\rightarrow h^{-} h^{(\prime)+}e^{+}e^{-}
$ ($ h^{(\prime)}=K,\,π$) decays with the dielectron mass
near the $η$ and $ϕ$ resonances, and away from these
resonances for the $ K^{+}K^{-}e^{+}e^{-} $ and $
π^{+}π^{-}e^{+}e^{-} $ modes. For these modes, we find no
significant signals and set 90$\\%$ confidence level upper
limits on their branching fractions at the
$\mathcal{O}$(10$^{-7}$) level.},
