The decay B0 → π0π0 was investigated. The analysis was based on the data sample collected with a Belle detector. It was assumed that neutral and charged B mesons are produced in equal amounts. A signal with a significance of 3.4 standard deviations was detected. The branching factor was also obtained by dividing the signal yield by reconstruction efficiency.
