Abstract

We report results from a search for the decay Bs0→ηη using 121.4 fb-1 of data collected at the (5S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We do not observe any signal and set an upper limit on the branching fraction of 14.3×10-5 at 90% confidence level. This result represents a significant improvement over the previous most stringent limit.

We do not observe any signal and set an upper limit on the branching fraction of 14.3×10-5 at 90% confidence level.
