Measurement of Time-Dependent $CP$ Asymmetries and the $CP$-odd Fraction in the Decay $B^0 \rightarrow D^{*+}D^{*-}$

Abstract : We present a measurement of time-dependent CP asymmetries and an updated determination of the CP-odd fraction in the decay B^0 --> D^{*+}D^{*-}. The measurements are derived from a data sample of 88 times 10^{6} B bar{B} pairs collected by the BaBar detector at the PEP-II energy asymmetric B Factory at SLAC. All results are preliminary.
