Abstract

We report the measurement of the branching fraction, the polarization, and the parameters of the time-dependent CP violation in B0→D* ⁺D* ^- decays using a data sample of 772×106BB̄ pairs, collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e ⁺e ^- collider. We obtain a branching fraction of B=(7.82±0.38±0.63) ×10 ^-4, a CP-odd fraction of R _⊥=0.138±0. 024±0.006 and, additionally, a fraction of the longitudinal component in the transversity base of R ₀=0.624±0.029±0.011. The measured values of the parameters of the CP violation are SD* ⁺D* ^-=-0.79±0.13±0.03 and AD* ⁺D* ^-=0.15±0.08±0.04.

N2 - We report the measurement of the branching fraction, the polarization, and the parameters of the time-dependent CP violation in B0→D* +D* - decays using a data sample of 772×106BB̄ pairs, collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e +e - collider. We obtain a branching fraction of B=(7.82±0.38±0.63) ×10 -4, a CP-odd fraction of R ⊥=0.138±0. 024±0.006 and, additionally, a fraction of the longitudinal component in the transversity base of R 0=0.624±0.029±0.011. The measured values of the parameters of the CP violation are SD* +D* -=-0.79±0.13±0.03 and AD* +D* -=0.15±0.08±0.04.
