Using 385 fb−1 of e+e− collisions, we study the amplitudes of the singly Cabibbo-suppressed decay D0→K−K+π0. We measure the strong phase difference between the ¯¯¯D0 and D0 decays to K∗(892)+K− to be −35.5°±1.9°(stat)±2.2°(syst), and their amplitude ratio to be 0.599±0.013(stat)±0.011(syst). We observe contributions from the Kπ and K−K+ scalar and …
