Abstract

We report a measurement of the CP-odd fraction and the time-dependent CP violation in B0→D*+D*- decays, using 657×106 BB̄ events collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We measure a CP-odd fraction of R=0.125±0.043(stat)±0.023(syst). From the distributions of the proper-time intervals between a B0→D*+D*- decay and the other B meson in the event, we obtain evidence of CP violation with measured parameters AD*+D*-=0.15±0.13(stat)±0.04(syst) and SD*+D*-=-0.96±0.25(stat)-0.16+0.13(syst).
