摘要
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.Received 23 January 2023Accepted 2 March 2023DOI:https://doi.org/10.1103/PhysRevD.107.L051101Published by the American Physical Society under the terms of the Creative Commons Attribution 4.0 International license.
