Improved measurement of time-dependent CP asymmetries and the CP-odd fraction in the decay B-0 -> D*D+*(-)

Improved measurement of time-dependent CP asymmetries and the CP-odd fraction in the decay B-0 -> D*D+*(-)

We present an updated measurement of the CP-odd fraction and the time-dependent CP asymmetries in the decay B0→D*+D*- using (383±4)×106BB̄ pairs collected with the BABAR detector. We determine the CP-odd fraction to be 0.143±0.034(stat)±0.008(syst). The time-dependent CP asymmetry parameters are det...
