Abstract
We present measurements of the branching fraction and time-dependent CP asymmetries in B^0→J/ψπ^0 decays based on (231.8±2.6)×10^6 Υ(4S)→BB decays collected with the BABAR detector at the SLAC PEP-II asymmetric-energy B factory. We obtain a branching fraction B(B^0→J/ψπ^0)=(1.94±0.22(stat)±0.17(syst))×10^(-5). We also measure the CP asymmetry parameters C=-0.21±0.26(stat)±0.06(syst) and S=-0.68±0.30(stat)±0.04(syst).
