Abstract

We report first observations of Bs0→J/ψη and Bs0→J/ψη^′. The 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 obtain the branching fractions B(Bs0→J/ψη)=[5.10±0.50(stat)±0. 25(syst)-0.79+1.14(N_Bs(*)B̄s(*))]×10 ^-4, and B(Bs0→J/ψη^′)=[3.71±0. 61(stat)±0.18(syst)-0.57+0.83(N_Bs(*)B̄s(*))] ×10^-4. The ratio of the two branching fractions is measured to be B(B_s→J/ψη^′)B(B_s→J/ ψη)=0.73±0.14(stat)±0.02(syst).
