Theoretical Particle Physics Research

我们的总体目标是通过各种现象学和理论研究来阐明物质的本质及其基本相互作用。欧洲核子研究中心大型强子对撞机（LHC）的新结果至关重要。拟议的研究将提高我们预测强相互作用（QCD）对LHC将研究的过程的影响的能力，并开发有效的方法来确定在那里发现的任何新物质状态的性质。解析和数值方法将被用来研究强子的性质，强相互作用的夸克束缚态。我们的研究将寻求确定强，弱和电磁相互作用的标准模型之外的内容，最终目标是提供一个完全统一的理论，包括引力。最有希望的候选理论将被研究，包括大统一和超弦统一以及具有额外空间维度的理论。实验室，天体物理学和宇宙学的影响将进行分析，以确定这些理论的最敏感的实验测试。我们希望这些研究将导致对质量起源的完整理解，包括对夸克，带电轻子和中微子质量，混合角和CP破坏以及暗物质性质的理解。除了与大型强子对撞机计划直接相关外，我们的研究还将与现在和未来的中微子和天体粒子实验以及天体物理学和宇宙学研究相关。特别是，将共同努力了解暗物质的性质，并优化检测直接和间接信号的策略。粒子物理模型的早期宇宙过程，如通货膨胀的影响也将进行研究，参考即将从普朗克有关可能的非高斯性的CMB各向异性和光谱特征，提供新的探测动力学的数据。将研究冰立方探测器（特别是平谷子阵列）用于研究大气中微子振荡的物理潜力。

Our overall aim is to elucidate the nature of matter and its fundamental interactions via a variety of phenomenological and theoretical studies. Of crucial importance will be the new results coming from the Large Hadron Collider (LHC) at CERN. The proposed research will improve our ability to predict the effects of the strong interactions (QCD) on the processes that will be studied at the LHC and develop efficient methods to determine the properties of any new states of matter discovered there. Both analytical and numerical methods will be used to study the properties of hadrons, strongly interacting bound states of quarks. Our research will seek to determine what lies beyond the Standard Model of the strong, weak and electromagnetic interactions, with the ultimate goal of providing a fully unified theory, including gravity. The most promising candidate theories will be studied, including Grand and superstring unification and theories with additional space dimensions. Laboratory, astrophysical and cosmological implications will be analysed to determine the most sensitive experimental tests of these theories. We hope these studies will lead to a complete understanding of the origin of mass, including an understanding of the quark, charged lepton and neutrino masses, mixing angles and CP violation, as well as of the nature of dark matter. In addition to having direct relevance to the LHC program, our research will have relevance to present and future neutrino and astroparticle experiments and to astrophysical and cosmological studies. In particular a concerted effort will be made to understand the nature of the dark matter and optimise strategies for detecting both direct and indirect signals. The implications of particle physics models for early universe processes such as inflation will also be studied, with reference to forthcoming data from Planck concerning possible non-gaussianity in the CMB anisotropy and spectral features which provide new probes of the dynamics. The physics potential of the IceCube detector (in particular the PINGU sub-array) for studying oscillations of atmospheric neutrinos will be investigated.
