$\Bz\to\pip\pim\piz$ Time Dependent Dalitz analysis at BaBar

Abstract

I present here results of a time-dependent analysis of the Dalitz structure of neutral $B$ meson decays to $\pip\pim\piz$ from a dataset of 346 million $B\bar{B}$ pairs collected at the ${\rm Y}(4S)$ center of mass energy by the BaBar detector at the SLAC PEP-II $e^{+}{e}^{-}$ accelerator. No significant CP violation effects are observed and 68% confidence interval is derived on the weak angle $\alpha$ to be [75${}^o$,152${}^o$]
