Resumen

Based on 7.33 fb-1 of e+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 Ds+→K+K+π- and Ds+→K+K+π-π0 are reported. We determine the absolute branching fraction of Ds+→K+K+π- to be (1.24-0.26+0.28(stat)±0.06(syst))×10-4. No significant signal of Ds+→K+K+π-π0 is observed and the upper limit on its decay branching fraction at 90% confidence level is set to be 1.7×10-4.
