Abstract: | 本篇論文嘗試在Belle 實驗的數據中尋找尚未被發現的新粒子。Belle 實驗是位於日本筑波的高能加速器研究機構B介子工廠透過不對稱能量的正負電子對對撞所進行的大型高能實驗。從實驗所獲得的龐大數據中,我們每次挑選二種不同種類的粒子進行組合,再從合併後計算出來的不變質量分布中檢查是否有未知的信號。最終我們並沒有觀察到任何未知的新粒子。 We try to search for new unknown particles at Belle. With the huge amount of data collected by Belle detector, we implied a simple method, direct combination with clean tag, to execute an extensive search. Finally, we didn’t observe any unknown particle in all results. |
