Abstract: We measure the branching fraction and time-dependent CP-violating asymmetry for B0?J/??0 decays using a data sample of 711 fb-1 collected on the (4S) resonance by the Belle experiment running at the KEKB e+e- collider. The branching fraction is measured to be B(B0?J/??0)=[1.62�0.11(stat)�0.06(syst)]�10-5, which is the most precise measurement to date. The measured CP asymmetry parameters are S=-0.59�0.19(stat)�0.03(syst) and A=-0.15�0.14(stat)+0.04-0.03(syst). The mixing-induced CP asymmetry (S) differs from the case of no CP violation by 3.0 standard deviations, and the direct CP asymmetry (A) is consistent with zero. � 2018 authors.
