Measurement of the $B^0\to \pi^0\pi^0$

We present a measurement of the branching fraction of the decay $B^0\to \pi^0\pi^0$, and a first measurement of the time-integrated CP asymmetry $C_{00}$, using a data sample of approximately 227 million BBar pairs collected by the BaBar detector at the PEP-II asymmetric-energy B Factory at SLAC. The signal has a significance of 5.0sigma.
