Electroweak Symmetry Breaking, Flavor Mixing and the LHC

拟议的研究计划旨在利用来自大型强子对撞机(LHC)和中微子实验的可用数据来回答粒子物理中长期存在的问题。这项研究的目的是为了加深我们对电弱对称破缺的本质以及风味混合和CP破缺的起源的理解。PI将通过构建超越标准模型物理的各种候选模型，并通过检查这些模型在大型强子对撞机和质子衰变和中微子地下实验中的实验结果，来解决粒子物理学中的这些悬而未决的问题。来自对撞机实验的新数据将被用来指导构建解决规范层次问题的模型，包括那些具有超对称性、额外维度和强耦合希格斯扇区的模型。将开发分析竞争模型之间的数据区分的方法。将分析这些模型中中微子的性质以及对质子衰变的影响。这些研究的结果可能指出了进一步统一肠道和家庭对称性的正确途径。我们将在额外维度或强耦合希格斯扇区中寻找CP破坏的新起源，并将研究它们对瘦子发生的影响。这项研究的结果将有望阐明宇宙中物质和反物质之间不对称的起源。我们将研究电弱对称性破缺背后的机制和风味混合动力学之间的可能联系。这项研究的更广泛影响是通过国际和平研究所积极参与加州大学欧文分校的夸克网络计划，促进公众对即将到来的令人兴奋的粒子物理结果的兴趣和欣赏。这些努力的补充是对研究生和博士后研究人员的培训，以及通过将本科生引入粒子物理研究的前沿。

The proposed research plans aim at utilizing the available data coming from the Large Hadron Collider (LHC) as well as neutrino experiments to answer long-standing questions in particle physics. The goal of this research is to further our understanding in the nature of electroweak symmetry breaking as well as the origin of flavor mixing and CP violation. The PI will approach these outstanding questions in particle physics by constructing various candidate models for beyond the standard model physics and by examining the experimental consequences of these models at the LHC and in underground experiments for proton decays and neutrinos. New data from Collider experiments will be utilized to guide the construction of models that solve the gauge hierarchy problem, including those with Supersymmetry, extra dimensions and a strongly coupled Higgs sector. Methods to analyze the data distinguish between competing models will be developed. Properties of the neutrinos and implications for proton decays in these models will be analyzed. The results of these studies may point to the right route to the further unification of GUT and the family symmetries. Novel origins of CP violation in extra dimensions or in a strongly coupled Higgs sector will be searched for, and their implications for leptogenesis will be studied. The outcome of this investigation willhopefully shed light on the origin of the asymmetry between matter and anti-matter in the Universe. Possible connections between the mechanism behind the electroweak symmetry breaking and the dynamics for flavor mixing will be investigated. The broader impacts of this research are to promote the public interests in and appreciations for the upcoming exciting results in particle physics, through an active participation of the PI in the UC Irvine's Quark Net Program. These efforts are complemented by the training of graduate students and postdoctoral researchers as well as by introducing undergraduate students into the frontiers of research in particle physics.
