Abstract

The question of whether the anomalously large B→Kη′ and B→Kη′X (inclusive) branching ratios are consistent with the standard model or a sign of new physics is still open and in the experimental court. The nature of the extra hadron X in B→Kη′X is completely unknown. Directions for investigation and analysis of inclusive data are suggested as well as for comparable inclusive data on B→KηX.New data confirming the prediction BR(K±ρ0)=BR(K±ω) support flavor-topology B→VP sum rules based on the OZI rule and emphasize the sharp contrast with the failure of the analogous B→PP sum rule due to the anomalously large BR(B→Kη′). Confirmation of OZI validity in B-decay analyses for VP final states suggests improving data on the analogous neutral decay difference BR(B0→K0ρ0)−BR(B0→K0ω) which measures tree-penguin interference and possible direct CP violation.A successful approximate isospin sum rule is rearranged and reinterpreted to pinpoint tree-penguin interference in B→Kπ and B→Kρ transitions. The magnitude of the interference is shown to still be at the statistical noise level with present data.
