Abstract

We report the results of the first search for the decay Bs0→π0π0 using 121.4 fb-1 of data collected at the ϒ(5S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We observe no signal and set a 90% confidence level upper limit of 7.7×10-6 on the Bs0→π0π0 decay branching fraction.
