Study of color suppressed modes $B^0\to {\bar{D}}^{(\ast )0}{\eta }^{(\prime )}$

Abstract

The color suppressed modes $B^0\to {\bar{D}}^{(\ast )0}{\eta }^{(\prime )}$ are analyzed in perturbative QCD approach. We find that the dominant contribution is from the non-factorizable diagrams. The branching ratios calculated in our approach for $B^0\to {\bar{D}}^{(\ast )0}\eta$ agree with current experiments. By neglecting the gluonic contribution, we predict the branching ratios of $B^0\to {\bar{D}}^{(\ast )0}{\eta }^{\prime }$ are at the comparable size of $B^0\to {\bar{D}}^{(\ast )0}{\pi }^0$, but smaller than that of $B^0\to {\bar{D}}^{(\ast )0}\eta$.
