Özet

Based on 7.33 fb-1 of e thorn e- collision data collected at center-of-mass energies between 4.128 and 4.226 GeV with the BESIII detector, the experimental studies of the doubly Cabibbo-suppressed decays D thorn s -> K thorn K thorn pi- and D thorn s -> K thorn K thorn pi-pi 0 are reported. We determine the absolute branching fraction of D thorn s -> K thorn K thorn pi- to be (1.24 thorn 0.28 -0.26 ostat thorn 0.06osyst thorn thorn x 10-4. No significant signal of D thorn s -> K thorn K thorn pi-pi 0 is observed and the upper limit on its decay branching fraction at 90% confidence level is set to be 1.7 x 10-4.
