Abstract: We present results for the branching fractions and charge asymmetries in B±→h±π0 (where h±=π±,K±) and a search for the decay B0→π0π0 using a sample of approximately 88×106 BB̅ pairs collected by the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We measure B(B±→π±π0)=(5.5-0.9+1.0±0.6)×10-6, where the first error is statistical and the second is systematic. The B±→π±π0 signal has a significance of 7.7σ including systematic uncertainties. We simultaneously measure the K±π0 branching fraction to be B(B±→K±π0)=(12.8-1.1+1.2±1.0)×10-6. The charge asymmetries are Aπ±π0=-0.03-0.17+0.18±0.02 and AK±π0=-0.09±0.09±0.01. We place a 90% confidence-level upper limit on the branching fraction B(B0→π0π0) of 3.6×10-6 .
