Abstract

Using

232 {fb}^{- 1}

e^{+} e^{-}

collision data recorded by the BABAR experiment, we measure the rates of three-body Cabibbo-suppressed decays of the

D^{0}

meson relative to the Cabibbo-favored decay,

D^{0} \to K^{-} π^{+} π^{0}

. We find:

\frac{B (D^{0} \to π^{-} π^{+} π^{0})}{B (D^{0} \to K^{-} π^{+} π^{0})} = (10.59 \pm 0.06 \pm 0.13) \times 10^{- 2}

and

\frac{B (D^{0} \to K^{-} K^{+} π^{0})}{B (D^{0} \to K^{-} π^{+} π^{0})} = (2.37 \pm 0.03 \pm 0.04) \times 10^{- 2}

, where the errors are statistical and systematic, respectively. These measurements are significantly more precise than the current world average measurements.
