Abstract

By analyzing 2.93fb −1 of data taken at the ψ(3770) resonance peak with the BESIII detector, we measure the branching fractions for the hadronic decays D + →K S 0 K S 0 K + , D + →K S 0 K S 0 π + , D 0 →K S 0 K S 0 and D 0 →K S 0 K S 0 K S 0 . They are determined to be B(D + →K S 0 K S 0 K + )=(2.54±0.05 stat. ±0.12 sys. )×10 −3 , B(D + →K S 0 K S 0 π + )=(2.70±0.05 stat. ±0.12 sys. )×10 −3 , B(D 0 →K S 0 K S 0 )=(1.67±0.11 stat. ±0.11 sys. )×10 −4 and B(D 0 →K S 0 K S 0 K S 0 )=(7.21±0.33 stat. ±0.44 sys. )×10 −4 , where the second one is measured for the first time and the others are measured with significantly improved precision over the previous measurements.
