We measure the branching fraction and time-dependent CP-violating asymmetry for B0 → J=ψπ0 decays using a data sample of 711 fb−1 collected on the ϒ(4S) resonance by the Belle experiment running at the KEKB e+e− collider. The branching fraction is measured to be B(B0 → J/ψπ0) ¼ [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 …
