Abstract

Using 385 fb − 1 of e + e − collisions, we study the amplitudes of the singly Cabibbo-suppressed decay D 0 → K − K + π 0 . We measure the strong phase difference between the ¯¯¯ D 0 and D 0 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 K π 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.
