Research in Elementary Particle Theory and Physics Theorynet Program

在不久的将来，大型强子对撞机（LHC）将投入使用，为粒子理论家探索太电子伏特区域基本相互作用的本质提供前所未有的机会。pi提出了一个详细的项目，用于分析大型强子对撞机的事件特征，这将为发现新物理学提供关键。提出了在大统一理论（GUTS）、弦理论和基于D膜的理论框架下对这种新物理的分析，包括与夸克带电的轻子-中微子织构和质子稳定性有关的问题。探测可能的tev级黑洞的最新特征将被探索。将研究可能的tev尺度弦激励对多胶子散射振幅的影响，这些振幅是多射流生产过程的基础。本文还提出了在大型强子对撞机的粒子（标准模型粒子的超对称伴侣）产生和衰变（在CMS和ATLAS探测器中）以及从大型强子对撞机的B衰变数据中测试CP违背模型。此外，额外的U(1)的物理可能是在对称破缺尺度以下的大统一和弦的残余物将被研究。在粒子天体物理学领域，一个主要的中微子望远镜（冰立方）将在几年内全面投入使用，一些高能伽马射线设施现在或将在不久的将来上线。提出的研究将展示如何在这些装置以及皮埃尔·奥格实验室地面阵列上进行测量，从而在天体物理学和粒子物理学、探测TeV尺度黑洞、量子退相干、光中微子质量的非跷跷板起源和中微子稳定性方面同时取得进展。该提案中提出的研究项目将以重要的方式为发现超越标准模型的新物理学做出贡献。这一发现将对未来几十年高能理论、弦理论和粒子天体物理学的发展产生重要影响。其中一位私人侦探托马斯·泰勒（Tomasz Taylor）是波士顿理论网外展计划的协调员。这个节目旨在向普通观众解释理论物理学家在高中课堂上对学生做了什么，以及在与理论家的个别会议上对教师做了什么。它的主要组成部分是物理学家、高中生和教师之间的直接互动，通过在常规上课时间访问和课后的问答和演讲。

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.
