| dc.description | Recently B-factories have published new results on the $B \to K ηγ$ decays being inspired by the theoretical suggestion to search for new physics in $B \to P_1 P_2 γ$ decays. Using heavy meson chiral perturbation theory we find mechanism which governs the amplitude in parts of the Dalitz plot where either $K$ or $η$ mesons are soft. The dominant contributions in these cases are coming from the nonresonant decay modes. We discuss also $B \to K η' γ$ Dalitz plot. Our partially integrated rates are in agreement with the experimental findings. | |
