Multiple Dalitz Plot Analysis At Cleo-C

<p>Dalitz Plot analysis is a standard technique for the study of weak hadronic 3-body decays. This technique allows us to extract the relative amplitudes, phases, and fit fractions of the resonances that are the primary product of such decays. A Dalitz analysis is complicated by the presence of two or more interfering resonances that appear at the same place on the plot. In this analysis I attempt to resolve the K⁰_s a₀(980)⁰ and K⁰_s f₀(980) in the decay of D⁰ \to K⁰_s K⁺ K^-. Using the K⁰_s a₀(980)⁰ resonance found in D⁰ \to K⁰_s π⁰ \eta, I compare equating a resonance in an interfering decay channel with a non--interfering channel by fit fraction or amplitude. I use the 818 pb^-1 of CLEO-c data collected a $\psi(3770)$ energies to perform the Dalitz plot analysis of D⁰ \to K⁰_s π⁰ \eta and D⁰ \to K⁰_s K⁺ K^-. I find large fractions from both K⁰_s a₀(980)⁰ and K⁰_s f₀(980) that destructively interfere to leave the K⁰_s \phi(1020) as the dominant resonance on the plot.</p>
