No significant signals are observed, and the corresponding upper limits on the branching fractions at the 90% confidence level are determined. The sensitivities of the results are at the level of 10(-5)-10(-6), providing a large improvement over previous searches.eninfo:eu-repo/semantics/openAccessSearch for the rare decays D -> h(h((')))e(+) e(-)Article2-s2.0-8504680424410.1103/PhysRevD.97.072015Q1WOS:000432958600002
