Measurement of time-dependent CP asymmetries and of the CP-odd fraction in the decay B->D*+D*-

Abstract

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