P. 231-237Abstract: By analyzing View the MathML source2.93fb−1 of data taken at the ψ(3770)ψ(3770) resonance peak with the BESIII detector, we measure the branching fractions for the hadronic decays View the MathML sourceD+→KS0KS0K+, View the MathML sourceD+→KS0KS0π+, View the MathML sourceD0→KS0KS0 and View the MathML sourceD0→KS0KS0KS0. They are determined to be View the MathML sourceB(D+→KS0KS0K+)=(2.54±0.05stat.±0.12sys.)×10−3, View the MathML sourceB(D+→KS0KS0π+)=(2.70±0.05stat.±0.12sys.)×10−3, View the MathML sourceB(D0→KS0KS0)=(1.67±0.11stat.±0.11sys.)×10−4 and View the MathML sourceB(D0→KS0KS0KS0)=(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.
