| 英文摘要 | Using the data samples of (1310.6 +/- 7.2) x 10(6) j/psi events and (448.1 +/- 2.9) x 10(6) psi(3686) events collected with the besiii detector, we search for the rare decays j/psi -> d(0)e(+) e(-) + c.c. and psi(3686) -> d(0)e(+) e(-) + c.c. no significant signals are observed and the corresponding upper limits on the branching fractions at the 90% confidence level are determined to be b(j/psi -> d(0)e(+) e(-) + c.c.) < 8.5 x 10(-8) and b(psi(3686) -> d(0)e(+) e(-) + c.c.) < 1.4 x 10(-7), respectively. our limit on b(j/psi -> d(0)e(+) e(-) + c.c.) is more stringent by 2 orders of magnitude than the previous results, and b(psi(3686) -> d(0)e(+) e(-) + c.c.) is measured for the first time. |
