Search for the rare decay D+→D0e+νe

Using a data set with an integrated luminosity of 2.93  fb−1 collected at s=3.773  GeV with the BESIII detector operating at the BEPCII storage rings, we search for the rare decay D+→D0e+νe. No signal events are observed. We set the upper limit on the branching fraction for D+→D0e+νe to be 1.0×10−4...

Description
Summary:Using a data set with an integrated luminosity of 2.93  fb−1 collected at s=3.773  GeV with the BESIII detector operating at the BEPCII storage rings, we search for the rare decay D+→D0e+νe. No signal events are observed. We set the upper limit on the branching fraction for D+→D0e+νe to be 1.0×10−4 at the 90% confidence level.
