In the near future the Large Hadron Collider (LHC) will come on line providing an unprecedented opportunity for particle theorists to probe the nature of fundamental interactions in the Tera-electronvolt region. The PIs present a detailed program for the analysis of event signatures at the LHC that would provide the key to the discovery of new physics. Analysis of such new physics in the framework of grand unified theories (GUTS), string theories, and theories based on D branes are proposed, including issues related to quark-charged lepton- neutrino textures and proton stability. Updated signatures for detection of possible TeV-scale black holes will be explored. The effects of possible TeV-scale string excitations in multi-gluon scattering amplitudes underlying multi-jet production processes will be investigated. It is also proposed to test models of CP violation in sparticle (Supersymmetric partners of Standard model particles) production and decays (in the CMS and the ATLAS detectors) at the LHC and from the data on B decays from LHCb. Additionally, physics of extra U(1)'s which may be the remnants of GUTs and strings below the symmetry breaking scale will be investigated. In the field of particle astrophysics, a major neutrino telescope (IceCube) will be operating at full acceptance in several years, and a number of high energy gamma ray facilities are online now or will be so in the very near future.The research proposed will show how measurements at these installations, as well as at the Pierre Auger Laboratory ground array, can permit simultaneous advances in astrophysics and particle physics, probing TeV scale black holes, quantum decoherence, non-seesaw origin of light neutrino masses and neutrino stability. The proposed research projects of this proposal will contribute in an important way to the discovery of new physics beyond the Standard Model. Such a discovery will have important implications for the development of high energy theory, string theory and particle-astrophysics in the coming decades. One of the PIs, Tomasz Taylor,is the coordinator of the Boston Theorynet outreach program. This program aims at explaining to general audiences what theoretical physicists do to students in high school classrooms and to teachers in individual meetings with theorists. Its main component is the direct interaction between physicists, high school students and teachers, through question and answer sessions and presentations during regular class hour visits and after class.

在不久的将来，大型强子对撞机（LHC）将在线上，为粒子理论家提供了前所未有的机会，以探测TERA-Electronvolt地区基本相互作用的性质。 PI提出了一个详细的程序，用于分析LHC的事件特征，该程序将为发现新物理学的关键提供关键。提出了对大统一理论（肠道），弦理论和基于d脑的理论的框架中对这种新物理的分析，包括与夸克·拉普顿（Quark）的Lepton-中微子纹理和质子稳定性有关的问题。将探索用于检测可能的TEV规模黑洞的更新签名。可能会研究可能的TEV尺度弦激兴激发在多luon散射幅度基础的多喷晶生产过程中的影响。还建议在LHC和LHCB的B衰减数据中测试生产中的CP违规模型（标准模型颗粒的超对称伙伴）和衰减（在CMS和ATLAS探测器中）。此外，将研究额外的u（1）物理学，这可能是对称性断裂量表以下的胆量和弦的残余物。 In the field of particle astrophysics, a major neutrino telescope (IceCube) will be operating at full acceptance in several years, and a number of high energy gamma ray facilities are online now or will be so in the very near future.The research proposed will show how measurements at these installations, as well as at the Pierre Auger Laboratory ground array, can permit simultaneous advances in astrophysics and particle physics, probing TeV scale black holes,量子反应，轻中微子质量的非透视起源和中微子稳定性。该提案的拟议研究项目将以重要的方式为发现标准模型以外的新物理学做出贡献。这种发现将对未来几十年的高能理论，弦理论和粒子骨质物理学的发展具有重要意义。 PIS之一Tomasz Taylor是波士顿理论网络外展计划的协调员。 该计划旨在向一般观众解释理论物理学家对高中教室中的学生和与理论家的个人会议中的教师所做的事情。它的主要组成部分是通过在常规课程访问和上课后的问会和演讲之间和回答会议和演讲之间的物理学家，高中生和老师之间的直接互动。
