Extraction of Axial Form Factors from Bbar0 --> D+ K- K{*0} Decay

Abstract

Based on Bbar to D{(*)}K-K{*0} decay data, which supports factorization, we propose to extract the kaon axial form factor in the factorization framework. Experiment indicates that the K-K{*0} pair is produced by an axial current where only one out of three axial form factors is dominant. The axial form factor can be extracted by fitting the K-K{*0} mass spectrum with an a_1(1260)-resonance plus QCD-motivated non-resonant contributions, which can be improved as data improves.
