Abstract

A search has been performed for the semileptonic decays D0 -> K0S K-e+nu_e, D+ -> K0S K0S e+nu_e and D+ -> K+K-e+nu_e, using 7.9 fb^-1 of e+e- annihilation data collected at the center-of-mass energy sqrt(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 x 10^-5, 1.54 x 10^-5, and 2.10 x 10^-5 for the branching fractions of D0 -> K0S K-e+nu_e, D+ -> K0S K0S e+nu_e and D+ -> K+K-e+nu_e, respectively.
