We report the results of the first search for the decay B0s→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 B0s→π0π0 decay branching fraction.

Abstract
We report the results of the first search for the decay B0s→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 B0s→π0π0 decay branching fraction.File in questo prodotto:
