B0bar decays to D(*)0 eta and D(*)0 eta'

Abstract

We consider the hadronic B decays B0bar -> D0 eta, B0bar -> D*0 eta, B0bar -> D0 eta', B0bar -> D*0 eta' in the framework of a quark-flavour basis and factorization. The formalism allows to compute the decays to the eta meson and to relate them to those of the eta'. Measuring the branching ratios of these processes may shed light on the nature of the eta-eta' mixing. On the experimental side, only upper limits on the branching ratios are known at present.
