Abstract

We present the first search for the leptonic decays D*+→e+νe and D*+→μ+νμ by analyzing a data sample of electron-positron collisions recorded with the BESIII detector at center-of-mass energies between 4.178 and 4.226 GeV, corresponding to an integrated luminosity of 6.32 fb−1. No significant signal is observed. The upper limits on the branching fractions for D*+→e+νe and D*+→μ+νμ are set to be 1.1×10−5 and 4.3×10−6 at 90% confidence level, respectively.
