Study of color suppressed modes B-0 ->(D)over-bar(()*()0)eta(()'())

The color suppressed modes B-0-->(D) over bar (()*()0)eta(()'()) are analyzed in the perturbative QCD approach. We find that the dominant contribution is from the nonfactorizable diagrams. The branching ratios calculated in our approach for B-0-->(D) over bar (()*()0)eta agree with current experiments. By neglecting the gluonic contribution, we predict that the branching ratios of B-0-->(D) over bar (()*()0)eta' are comparable in size to those for B-0-->(D) over bar (()*()0)pi(0), but smaller than those for B-0-->(D) over bar (()*()0)eta.
