英文摘要 | We search for rare decays of d mesons to hadrons accompanied by an electron-positron pair (h(h((')))e(+)e(- )),using an e(+)e(-) collision sample corresponding to an integrated luminosity of 2.93 fb(-1) collected with the besiii detector at root s = 3.773 gev. 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. |
