Description
A search for the process $e^{+}e^{-} \to D^{*0}(2007)$ has been performed with the CMD-3 detector at the VEPP-2000 $e^{+}e^{-}$-collider. Two main decay modes $D^{0}\pi^{0}$ and $D^{0}\gamma$ with $D^{0} \to K^{+}\pi^{-}\pi^{+}\pi^{-}$ and $D^{0} \to K^{+}\pi^{-}\pi^{0}$ are used in this analysis. Using an integrated luminosity of $25.5~ nb^{-1}$ collected at the center-of-mass energy $E_{c.m.} = 2006.62~\rm MeV$ we preliminary get an upper limit for $\mathcal{B}(D^{*0}\to e^+e^−) < 6\times 10^{-7}$ at 90% C.L.
