Abstract

We have searched for Bs0→hh decays, where h stands for a charged or neutral kaon, or a charged pion. These results are based on a 23.6fb-1 data sample collected with the Belle detector on the Υ(5S) resonance at the KEKB asymmetric-energy e^+e- collider, containing 1.25×106 Bs(*)B̄s(*) events. We observe the decay Bs0→K ^+K- and measure its branching fraction, B(Bs0→K ^+K-)=[3.8-0.9+1.0(stat)±0.5(syst)±0.5(f _s)]×10^-5. The first error is statistical, the second is systematic, and the third error is due to the uncertainty in the Bs0 production fraction in e^+e-→bb̄ events. No significant signals are seen in other decay modes, and we set upper limits at the 90% confidence level: B(Bs0→K-π+)<1.2×10^-5, B(Bs0→π+π-)<2.6×10^-5, and B(Bs0→K0K̄0) <6.6×10^-5.
