$\bar{B}^0$ decays to $D^{(*)0} \eta$ and $D^{(*)0}\eta^\prime$

Abstract.

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