Together with several currently running and planned experiments, many of the outstanding problems of modern particle physics may soon find their answers. To play a more significant role in this exciting period, this Subproposal (SP) aims at building up the Theory-Experiment link, to unify the current frontiers in heavy flavor, electroweak symmetry breaking (EWSB) and neutrino physics. We wish to emulate the success of the B physics support to Belle, and extend to other experiments under the main proposal: CMS Analysis (SP-1); From Belle to SuperBelle (SP-2); Daya Bay Neutrino Oscillation Experiment (SP-3); and NuTel — A Neutrino Telescope in Taiwan for τ Appearance (SP-4). The main goal of LHC is to understand the mechanism for EWSB, hence mass generation. The initial physics goal of SP-1 is to pursue the search for the 4th generation b’ quark with the CMS detector covering the whole mass range allowed by weak Higgs mechanism. This is one of the strengths of our theory faculty, with this steppingstone, we will be able to study any type of new heavy particle thereafter. The CP properties of Higgs boson, and other possible new physics effects will also be pursued with LHC data, and feedback on our future experimental program. B physics is our strong suit, where we have made significant contributions to Belle, such as strong theoretical input to the two best possible indications for new physics, B decay to baryons, and effects of 4th generation quark. SP-2 joins the B-factory upgrade at KEK, to open up further opportunities for discovery. We will emphasize on CP violation, quark mixing in B decays, as well as the new hot topic on heavy hadron spectroscopy. With recent dramatic progress in neutrino physics, SP-3 pursues 13, the 3rd neutrino mixing angle, and SP-4 develops the novel NuTel neutrino telescope to study  appearance, even detect possible AGN source for UHECR. Whether 13 is zero or not is of fundamental importance, since CP violation in neutrino oscillations depends on it. We have independently proposed the tri-bi-maximal mixing which explains current data well and predicts 13 to be zero before. We will focus on models for neutrino mass and mixing, their implications for leptogenesis, sterile neutrinos, and cosmic neutrino production mechanisms. The above directions all come back to the Question of Mass. This proposal will link different experimental efforts to provide better synthesis of our understanding. Theory work certainly has a life of its own, therefore we will also work on a broader range of theoretical topics, such as model building beyond SM, unification of forces in Nature, unparticles, dark energy and dark matter in particle context. In theoretical studies, quality manpower at critical mass is necessary. This proposal aims at planning to gradually build up several layers of research staff. In the initial stage we will aim at recruiting 2 to 3 high caliber researchers working in the areas of collider and beyond SM physics. This effort will therefore put NTU in a better position to compete for hosting the NCTS.關鍵字質量生成弱電對稱破缺重味夸克微中子赫格斯粒子CP破缺輕子數生成機制理論—實驗連結Keywords: mass generationEWSBheavy flavorneutrino mixingHiggsCP violationleptogenesistheory-experiment link
