title = "Search for the semileptonic decay Ds+ →π0e+νe",
abstract = "We present the first search for the semileptonic decay Ds+→π0e+νe using 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. This decay is expected to be sensitive to π0-η mixing. No significant signal is observed. We set an upper limit of 6.4×10-5 on the branching fraction at the 90% confidence level.",
