Abstract

We report the observation of Bs0→J/ψf0(980) and evidence for Bs0→J/ψf0(1370), which are CP eigenstate decay modes. These results are obtained from 121.4fb-1 of data collected at the Υ(5S) resonance with the Belle detector at the KEKB e +e- collider. We measure the branching fractions B(Bs0→J/ψf0(980);f0(980) →π+π-)=(1.16-0.19+0.31(stat)-0.17+0.15(syst)-0. 18+0.26(NBs(*)B̄s(*)))×10-4 with a significance of 8.4σ, and B(Bs0→J/ψf0(1370);f 0(1370)→π+π-)=(0.34-0.14+0.11(stat) -0.02+0.03(syst)-0.05+0.08(NBs(*)B̄s(*))) ×10-4 with a significance of 4.2σ. The last error listed is due to uncertainty in the number of produced Bs(*)B̄s(*) pairs.
