Abstract: We present a study of the decay B0→π0π0 based on a sample of 124×106 BB̅ pairs recorded by the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We observe 46±13±3 events, where the first error is statistical and the second is systematic, corresponding to a significance of 4.2 standard deviations including systematic uncertainties. We measure the branching fraction B(B0→π0π0)=(2.1±0.6±0.3)×10-6, averaged over B0 and B̅ 0 decays.
