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*- using a data sample of 88x10(6)B (B) over bar pairs collected by the BABAR detector at the PEP-II B Factory at SLAC. We determine the CP-odd fraction to be 0.063+/-0.055(stat)+/-0.009(syst). The time-dependent CP asymmetry parameters Im(lambda(+)) and \lambda(+)\ are determined to be 0.05+/-0.29(stat)+/-0.10(syst) and 0.75+/-0.19(stat)+/-0.02(syst), respectively. The standard model predicts these parameters to be -sin2beta and 1, respectively, in the absence of penguin diagram contributions.
