過去雙光子反應中強子對生成機制研究，引導我們深入瞭解夸克形成粒子過程。此研究擬藉由不同三體終態，如e計e訃淪 DDX，訕訕淪 晉 晉訃釘，計 訕訕淪 書畝晉計 S 或訕訕淪 畝畝X ，探討更大動態範圍及自由度下，粒子形成的過程。比較不同反應中相似點，如 e計e訃淪 DD釘計釘訃 及訕訕淪 畝畝(釘計釘訃) 反應過程中之(釘計釘訃) 或訕訕淪 書畝晉計 之晉計 與訕訕淪 畝畝釘0 之釘0，可直接驗證量子色動力學的基本理論。它們代表著膠子」轉化」成強子的過程。本計劃擬逐年深入探討量子色動力學中膠子如何由真空產生夸克，進而形成粒子的過程。可能在幾年之後直接探索真空的本質。此外，中大Belle 小組正主導Belle Grid 建立，本年度將擴大Belle VO 建立及運行，是將Belle 實驗引入與世界接軌關鍵的一年。 In past years our studies focused on the production mechanism of hadron pairs in two-photon collisions. Such studies reveal how quarks form hadrons. We believe that wider dynamical ranges and freedom rendered by three-body final states, such as e+e- 逕 DDX, 訕訕逕 Ks 0K-p+, 訕訕逕 書畝K+ or 訕訕逕 P 畝X, shall extend our understanding of such process. Fundamentals of QCD can be verified if similarities from different processes are extracted, e.g. 釘+洶釘- system in e+e- 逕 D D 釘+洶釘- and in 訕訕逕 P 畝釘+洶釘- or K+ in 訕訕逕 書畝K+ and 釘0 in 訕訕逕 P 畝釘0. Those similarities represent how gluons convert into hadrons. This proposal studies how gluon creates quarks in vacuum and consequently quarks form hadrons in QCD processes. Three-body final states in e+e- annihilation processes and in two-photon collisions are our experimental samples. Property of vacuum shall be revealed as our study continues in the coming years. NCU Belle group has been engaging in Belle grid project and playing a major role. This coming year should be critical because more Belle VO will be extended and large scale operation will be deployed. The success of this operation will introduce Belle experiment to globalization platform. 研究期間：9608 ~ 9707
