Abstract

We report on a search for $C P$ asymmetry in the singly Cabibbo-suppressed decay $D^{+} \to K^{+} K^{-} π^{+}$ using a data sample of $818 {pb}^{- 1}$ accumulated with the CLEO-c detector on the $ψ (3770)$ resonance. A Dalitz-plot analysis is used to determine the amplitudes of the intermediate states. We find no evidence for $C P$ violation either in specific two-body amplitudes or integrated over the entire phase space. The $C P$ asymmetry in the latter case is measured to be $(- 0.03 \pm 0.84 \pm 0.29) %$ .
