Abstract
We study the time-dependent Dalitz plot of in decays, where is a , , , or meson and , using a data sample of decays collected with the BABAR detector. We determine , , and , where the first error is statistical, the second is the experimental systematic uncertainty, and the third, where given, is the Dalitz model uncertainty. Assuming the world average value for and , is preferred over at 86% confidence level.
