• By analyzing 2.93 fb−1 of data taken at the ψ(3770) resonance peak with the BESIII detector, we measure the branching fractions for the hadronic decays D+→K0SK0SK+, D+→K0SK0Sπ+, D0→K0SK0S and D0→K0SK0SK0S. They are determined to be B(D+→K0SK0SK+)=(2.54±0.05stat.±0.12sys.)×10−3, B(D+→K0SK0Sπ+)=(2.70±0.05stat.±0.12sys.)×10−3, B(D0→K0SK0S)=(1.67±0.11stat.±0.11sys.)×10−4 and B(D0→K0SK0SK0S)=(7.21±0.33stat.±0.44sys.)×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.
