A search has been performed for the semileptonic decays D0→KS0K-e+νe, D+→KS0KS0e+νe, and D+→K+K-e+νe, 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+νe, D+→KS0KS0e+νe, and D+→K+K-e+νe, respectively.

Abstract
A search has been performed for the semileptonic decays D0→KS0K-e+νe, D+→KS0KS0e+νe, and D+→K+K-e+νe, 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+νe, D+→KS0KS0e+νe, and D+→K+K-e+νe, respectively.File in questo prodotto:
