Abstract:	We search for the decay Bs0??? and measure the branching fraction for Bs0??? using 121.4 fb-1 of data collected at the (5S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. The Bs0??? branching fraction is measured to be (3.6�0.5(stat)�0.3(syst)�0.6(fs))�10-5, where fs is the fraction of Bs(?)B�s(?) in bb� events. Our result is in good agreement with the theoretical predictions as well as with a recent measurement from LHCb. We observe no statistically significant signal for the decay Bs0??? and set a 90% confidence-level upper limit on its branching fraction at 3.1�10-6. This constitutes a significant improvement over the previous result. � 2015 American Physical Society.
