Extraction of Axial Form Factors from Bbar0 --> D+ K- K*0 Decay
Chun-Khiang Chua, Wei-Shu Hou, Shang-Yuu Tsai
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 a1(1260)-resonance plus QCD-motivated non-resonant contributions, which can be improved as data improves.
