Abstract

We report the observation of B̄0→D0η′ and the first observation of B̄0→D*0η′, using 140fb-1 of data collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric energy e+e- collider. We find the branching fractions to be B(B̄0→D0η′)=[1.14±0.20(stat)+0.10-0.13(syst)] ×10-4 and B(B̄0→D*0η′)=[1.21±0.34(stat) ±0.22(syst)]×10-4 with significances including systematic uncertainties of 8.9 and 5.3 standard deviations, respectively.
