Özet
A search has been performed for the semileptonic decays D0?KS0K-e+?e, D+?KS0KS0e+?e, and D+?K+K-e+?e, using 7.9 fb-1 of e+e- annihilation data collected at the center-of-mass energy s=3.773 GeV by the BESIII detector operating at the BEPCII collider. No significant signals are observed, and upper limits are set at the 90% confidence level of 2.13×10-5, 1.54×10-5, and 2.10×10-5 for the branching fractions of D0?KS0K-e+?e, D+?KS0KS0e+?e, and D+?K+K-e+?e, respectively. © 2024 authors.
