    簡要記述(中)：末態含有兩個向量介子(V)的無魅衰變B→VV有三個偏極態，理論上預期這種衰變主要來自於縱偏極化，而橫向偏極化相當小。但是2004年B介子工廠BaBar及Belle發現到横偏極化和縱偏極化一樣重要，這個實驗的結果令人相當困惑，很多物理學家提出各種不同的機制來解釋該現象，但是大部分的機制都相當牽強。鄭海揚研究員及中原大學的楊桂周教授發現到下一階的非因次化效應（包括頂點修正、企鵝圖修正及旁觀者散射）可以成功地解釋為什麼橫偏極化的振幅扮演重要的角色[1]，我們也推廣到末態含有軸向量介子的衰變，即B→AA,VA
    簡要記述(英)：Charmless two-body B decays into final states involving two vector mesons (VV) consist of three polarization states. Naively, it is expected that this decay is dominated by the longitudinal polarization, while the transverse polarization is very small. However, since 2004 B factories BaBar and Belle have found that transverse polarization is of the same magnitude as the longitudinal one for penguin-dominated charmless decays. Various mechanisms have been put forward to resolve this polarization fraction puzzle, but most of them are not appealing and satisfactory. Dr. Hai-Yang Cheng of Academia Sinica and Prof. Kwei-Chou Yang of Chung Yuan Christian University discovered that next-to-leading-order nonfactorizable effects (including vertex, penguin corrections and hard spectator scattering) can naturally explain why the transverse polarization can be large and plays an essential role [1]. They have extended their study to final states involving one or two axial-vector mesons, i.e. .
