The authors' main claim We find the Dalitz Plot is well represented by a combination of seven quasi-two-body decay channels ($\bar{K}^{*0} \pi^0$, $K^- \rho$, $K^{*-} \pi^+$, $K^*_0(1430)^-\pi^+$, $\bar{K}^*_0(1430)^0 \pi^0$, $K^- \rho^+(1700)$, and $K^*(1680)^- \pi^+$), plus a small non-resonant component.

The compiled record

The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. Numbers in the tables are the authors', checked by code. No sentence in this record was written by a model.

The abstract, sentence by sentence

arXiv listing abstract v2. Results and the main claim are underlined; .

We use data collected with the CLEO II detector to perform a high-statistics measurement of the resonant substructure in $D^0 \to K^-\pi^+\pi^0$ decays. We find the Dalitz Plot is well represented by a combination of seven quasi-two-body decay channels ($\bar{K}^{*0} \pi^0$, $K^- \rho$, $K^{*-} \pi^+$, $K^*_0(1430)^-\pi^+$, $\bar{K}^*_0(1430)^0 \pi^0$, $K^- \rho^+(1700)$, and $K^*(1680)^- \pi^+$), plus a small non-resonant component. Using the amplitudes and phases from this analysis, we calculate an integrated CP asymmetry of $-0.031 \pm 0.086$.
