| dc.description.abstract | 本篇論文著重在提出B介子稀有衰變至二體強子〈含ω介子〉於改善方法學後之量測結果。使用數據為來自日本〈位於筑波〉之高能加速器中心〈KEKB〉所屬之B介子工廠〈Belle〉：係由不對稱能量之正負電子對對撞而產生之。
我們測量到B+/-到ωK+/-, B+/-到ωπ+/-和B0到ωK0的稀有衰變率；更重要的是，在前二者尋找衰變中正負電荷分支比之不對稱性。此外，我們也尋找B0到ωπ0和B0到ωη：同時考慮η到γγ及η到π+π-π0的其中兩種次衰變模式。 | zh_TW |
| dc.description.abstract | We report improved measurements of two bodies hadronic B meson to psudoscalar-vector decays with a ω meson in the final state using data collected with the Belle detector at KEKB asymmetric-energy e+e- collider located at the High Energy Accelerator Research Organization, Tsukuba, Japan.
We measure the branching fractions of B+/- to ωK+/-, B+/- to ωπ+/-, and B0 to ωK0 at the same time, and most important of all, the direct C (charge) P (parity) asymmetries for the first two modes. Also, we search for the decays B0 to ωπ0 and B0 to ωη, where both the sub-decay channels: η to γγ and η to π+π-π0 are considered. | en |
