Observation of B0bar --> D0 eta' and B0bar --> D*0 eta'

Abstract

We report the observation of B0bar --> D0 eta' and the first observation of B0bar --> D*0 eta', using 140 fb-1 of data collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric energy e+ e- collider. We find the branching fractions to be B(B0bar --> D0 eta') = [ 1.14 +- 0.20(stat) +0.10-0.13(syst)] x 10^-4 and B(B0bar --> D*0 eta') = [ 1.21 +- 0.34(stat) +- 0.22(syst)] x 10^-4 with significances including systematic uncertainty of 8.9 and 5.3 standard deviations, respectively.
