Abstract

Using 385fb-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 D̄0 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 vector amplitudes, and analyze their angular moments. We find no evidence for charged κ, nor for higher spin states. We also perform a partial-wave analysis of the K-K+ system in a limited mass range.
