dc.description.abstractUsing 2.93 fb-1 of e+e- collision data collected at a center-of-mass energy of 3.773 GeV with the BESIII detector, we present a measurement of the branching fraction of the doubly Cabibbo-suppressed (DCS) decay D0?K+?-?0 and a search for the DCS decay D0?K+?-?0?0. The branching fraction of D0?K+?-?0 is determined to be [3.13-0.56+0.60(stat)±0.15(syst)]×10-4. No signal is observed for D0?K+?-?0?0, and an upper limit of 3.6×10-4 is set on the branching fraction at the 90% CL. We combine these results with the world-average branching fractions of their counterpart Cabibbo-favored decays to determine the ratios of the DCS over the Cabibbo-favored branching fractions, B(D0?K+?-?0)/B(D0?K-?+?0)=(0.22±0.04)% and B(D0?K+?-?0?0)/B(D0?K-?+?0?0)<0.40% at the 90% CL which correspond to (0.75±0.14)tan4?C and 1.37×tan4?C, respectively, where ?C is the Cabibbo mixing angle. © 2022 authors.
