Abstract

We present an updated measurement of time-dependent CP asymmetries and the CP-odd fraction in the decay B0→D*+D*- using 232×106BB» pairs collected by the BABAR detector at the SLAC PEP-II B factory. We determine the CP-odd fraction to be 0.125Â±0. 044(stat)Â±0.007(syst). The time-dependent CP asymmetry parameters C+ and S+ are determined to be 0.06Â±0.17(stat)Â±0. 03(syst) and -0.75Â±0.25(stat)Â±0.03(syst), respectively. The standard model predicts these parameters to be 0 and -sinâ□¡2Î, respectively, in the absence of penguin amplitude contributions.
