Abstract

A search for the process e<superscript>+</superscript>e<superscript>−</superscript>→ D<superscript>*0</superscript>(2007) has been performed with the CMD-3 detector at the VEPP-2000 e<superscript>+</superscript>e<superscript>−</superscript>-collider. Two main decay modes of the D<superscript>*0</superscript>(2007) decay, D<superscript>0</superscript>π<superscript>0</superscript> and D<superscript>0</superscript>γ, followed by D<superscript>0</superscript> → K<superscript>+</superscript>π<superscript>−</superscript>π<superscript>+</superscript>π<superscript>−</superscript>are used in this analysis. With an integrated luminosity of 3.7 pb<superscript>−1</superscript> collected at the center-of-mass energy E<subscript>c.m.</subscript> =2006.62 MeV our preliminary upper limit is B<subscript>D*<superscript>0</superscript>→e+ e−</subscript> <1.6× 10<superscript>−6</superscript> at 90%C.L.
