摘要:	計畫主持人對於基礎理論真正主要領域的研究--尤其是改善我們對基礎物理學概念上的理解--有所興趣。最近，他致力於兩個主要方面---超越標準模型的粒子理論和量子時空與重力理論的新途徑。從最近的努力我們認為已達成很大的進展。本計畫申請書希望能得到經費提供以支持繼續研究。本計畫申請書涵蓋了2010年到2013年,其亦為高能物理現象學領域的特殊關鍵時期。大型強子對撞機預計不久後將開始做超越標準模型物理尺度的探索，為弱電對稱破缺的來源及其之外的物理開啟一扇明亮的窗。連結到對模型建構的努力，我們小組已從許多不同的面向研究了希格斯粒子及超越標準模型現象學。包括超對稱標準模型（不論有無R宇稱）、無手征性規範異常小希格斯模型、標準模型費米子家族架構的規範對稱模型等等，都是我們努力的範疇。最近，我們發現一個新的動力學對稱破缺模型，其可作為超對稱標準模型的背景弱電對稱性破缺模型。這是一個重要的突破，我們也打算繼續以該研究方向作為一個重點。自2006年以來，我們開始將一激進的量子時空新理論公式化。在基礎對稱性上，透過將普朗克常數視作類似光速的基礎物理量並藉由穩定化李代數引進其數學結構，量子時空的相對性對稱已被辨識。我們未來的計劃主要側重於我們所提出的中介相對論的物理研究，以期得到跟該理論建構相關且實驗上可檢驗的結果。 The principal investigator is interested on researches on the true main fronts of fundamental theory, especially on improving our conceptual understanding of fundamental physics. Recently, he has been launching attacks on two main fronts --- particle theory beyond the Standard Model (SM) and a new approach to the theory of quantum space-time and gravity. We think quite substantial progresses have been achieved from our recent efforts. This grant project proposal asks for support to continue that. This grant project proposal covers the year 2010 to 2013, which is a special critical period for the field of high energy phenomenology. The Large Hadron Collider is expected to start probing beyond the scale of SM physics soon, opening up a clear window towards the origin of the physics of electroweak symmetry breaking and beyond. Our group has studied various aspects of Higgs and other aspects of beyond SM phenomenology in close connection with our model building efforts. The supersymmetric SM with or without R parity, chiral anomaly free little Higgs models, and gauge symmetry models for the structure of SM fermion families have been among our efforts. Most recently, we find a new dynamical symmetry breaking model as the background electroweak symmetry breaking model for the supersymmetric SM. This is an important breakthrough we also intend to pursue as a main focus. We started formulating a radical new theory for the quantum space-time since 2006. The relativity symmetry for the quantum space-time is identified through Lie algebra stabilization with the Planck’s constant giving a similar role as the speed of light in fixing the fundamental symmetry. Our future plan focuses mostly on studying the physics of an intermediate relativity we just introduced to get to plausible experimentally accessible features related to the formulation. 研究期間：9908 ~ 10007
