Abstract
We present measurements of the branching fraction and time-dependent CP asymmetries in B0→J/ψπ0 decays based on (231.8±2.6) ×106Υ(4S)→BB̄ decays collected with the BABAR detector at the SLAC PEP-II asymmetric-energy B factory. We obtain a branching fraction B(B0→J/ψπ0)=(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). © 2006 The American Physical Society.
