Abstract

We compute B->K eta' branching ratio using perturbative QCD approach. We show that a triangular relation among amplitudes for B^0->K^0 pi^0, B^0->K^0 eta, B^0->K^0 eta' receives large corrections from SU(3) breaking effects. If experimental value will come closer to the lower limit of the present BELLE data there will be a possibility to understand the large branching ratio of B^0->K^0 eta'. Otherwise, we perhaps need to modify our understanding of eta' meson, for example, inclusion of a possible admixture of gluonium state.
