| dc.description.abstract | We report the results of the first search for the decay B_s^0 → π^0 π^0 using 121.4 fb^{-1} of data collected at the Υ(5S) resonance with the Belle detector at the KEKB asymmetric-energy electron-positron collider. We observe no signal and set a 90% confidence level upper limit of 7.7×10^{-6} on the B_s^0 → π^0 π^0 decay branching fraction. Our result constitutes the first stringent upper limit set by the Belle experiment for this decay channel. | en_US |
