Abstract

Implications of the recent new measurements of B → K by Belle are examined. It is shown that the new branching ratio B[B → K1(1270)γ] requires very large form factor compared to the theoretically predicted one. This is an opposite case to B → K*γ where theory expected larger branching ratio. Possible origins of the discrepancy are discussed.
