Abstract:
We report results from a search for the decay
B$_{s}$$^{0}$ →ηη 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 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.
