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 $D^{0} \to K^+\pi^-\pi^+\pi^-$ are used in this analysis. Using an integrated luminosity of 3.7 pb$^{−1}$ collected at the center-of-mass energy Ec.m.=2006.62 MeV we preliminary get an upper limit for B$_{D^{0*} \to e+e−}$<1.7*$10^{-6}$ at 90% C.L.
