论文摘要
我们讨论了$ b $ -Meson衰减形式的一般属性$ f（q^2，q'^2）$，描述了$ b $ -Meson的衰减，例如两种电流引起的衰减，例如，在最终状态下，$ b $ decte to to to to the the Lines状态。我们研究这些复杂对象的分析性能，并确定$ q^2 $和$ q'^2 $的那些区域，其中可以应用扰动qCD来获得对物理形态的预测。
We discuss the general properties of the $B$-meson decay form factors $F(q^2,q'^2)$, describing $B$-meson decays induced by two currents, e.g., $B$-decays into four leptons in the final state. We study the analytic properties of these complicated objects and identify those regions of $q^2$ and $q'^2$, where perturbative QCD can be applied for obtaining predictions for the physical form factors.
