Abstract

We consider the hadronic B decays B⁰→ D⁰η, B⁰ → D^*0η, B⁰→ D⁰η', B⁰ → D^*0η' in the framework of a quark-flavour basis and factorization. The formalism allows one to compute the decays to the η meson and to relate them to those of the η'. Measuring the branching ratios of these processes may shed light on the nature of the η--η' mixing. On the experimental side, only upper limits on the branching ratios are known at present.
