Abstract

We have studied the Cabibbo-suppressed decay mode D0→K+K-π0 using a Dalitz plot technique and find the strong phase difference δD≡ δK*-K+-δK*+K-=332°±8°±11°and relative amplitude rD≡K*-K+/aK*+K-=0.52±0.05±0. 04. This measurement indicates significant destructive interference between D0→K+(K-π0)K*- and D0→K-(K+π0)K*+ in the Dalitz plot region where these two modes overlap. This analysis uses 9.0fb-1 of data collected at s≈10.58GeV with the CLEO III detector.
