Measurement of time-dependent conjugation (C) and parity (P) asymmetries and the CP-odd fraction in the decay B0→D*+D *- was discussed. It was found that this measurement of R⊥ supersedesthe BABAR results with a factor of 3 reduction in statistical uncertainty. Results also showed that B0→D*+D*- is mostly CP even.
