Limits on $D^0$-$\bar D^0$ mixing and $CP$ violation from the ratio of lifetimes for decay to $K^-\pi^+$, $K^-K^+$, and $\pi^-\pi

We present a measurement of $D^0$-$\D0bar$ mixing parameters using the ratios of lifetimes extracted from samples of $D^0$ mesons decaying to $K^-\pi^+$, $K^-K^+$, and $\pi^-\pi^+$. Using 91 ${\rm fb}^{-1}$ of data collected by the BaBar detector at the PEP-II asymmetric-energy $B$ Factory, we obtai...
