Abstract: We measure the branching fraction and CP violation asymmetry in the decay B0 ? ?0?0, using a data sample of 752 � 106 BB� pairs collected at the ?�4S� resonance with the Belle detector at the KEKB e�e? collider. The obtained branching fraction and direct CP asymmetry are B�B ? ?0?0� � �1.31 0.19�stat� 0.19�syst� � 10?6 and ACP � �0.14 0.36�stat� 0.10�syst�, respectively. The signal significance, including the systematic uncertainty, is 6.4 standard deviations. We combine these results with Belle�s earlier measurements of B0 ? ?�?? and B ? ??0 to exclude the CP-violating parameter ?2 from the range 15.5� < ?2 < 75.0� at 95% confidence level. � 2017 American Physical Society.
