项目摘要

The proposed research joins scientists of the particle theory groups at Sussex, Royal Holloway and University College London in the hunt for new physics under four broad headings:Collider and low-energy phenomenology:The Large Hadron Collider boosts elementary particles to velocities so close to that of light that their effective mass grows by a factor of a billion. By smashing these particles together there are new discoveries to be made, and new theories of physics to test. We will work on the complex task of relating the debris of these collisions to the new models put forward by theorists to explain some of the most puzzling questions of the universe - what is the origin of mass? and is there a quantum theory of gravity?Particle astrophysics and cosmology:One of the most active areas of research in the past decade has been at the interface between particle physics and cosmology. In order to understand the history of the Universe we must understand physical laws in the first moments of the Big Bang, when temperatures and particle energies were huge. Conversely, by detailed observations of the universe today we can trace back the conditions and make deductions about physical laws at high energies. Our research will tackle big questions about the universe: why is there more matter than antimatter? what is the nature of neutrinos and dark matter? can we use gravitational waves to look at the first picoseconds of the Universe? how can the new quantum technology be used to search for dark matter and other invisible particles? and how can quantum theory and gravity be combined, and can we see their joint effects in the cosmos?Fixed points of quantum field theory:The recent discovery that Standard Model-like theories can be fundamental and predictive up to highest energies without being asymptotically free has opened a door into uncharted territory. These novel theories offer alternative ways to UV complete the Standard Model and to address its open challenges from an entirely new angle. Our research will focus on the systematic evaluation of these new types of theories, including the construction of benchmark models beyond the Standard Model. We combine these studies with our continuing quest towards a quantum version of general relativity. Predictions of these scenarios will be contrasted with data from particle colliders and cosmology.Tools for high energy physics:The high-luminosity LHC (HL-LHC) was announced as top priority of the European Strategy for Particle Physics and will dominate collider physics in the next decade. The aim of this science area is to improve tools for phenomenologically relevant BSM scenarios so that they meet the needs of the HL-LHC.

拟议的研究与萨塞克斯郡，皇家霍洛威和伦敦大学学院的粒子理论小组的科学家一起寻找了四个广阔的标题下的新物理学：对撞机和低能现象学：大型强子对撞机将基本颗粒提升到速度，以使其接近光线的速度，以至于它们的有效质量增长了数十亿个因素。通过将这些粒子粉碎在一起，可以制定新的发现，以及可以测试的新理论。我们将处理将这些碰撞碎片与理论家提出的新模型联系起来的复杂任务，以解释宇宙中一些最令人困惑的问题 - 弥撒的起源是什么？是否有重力理论？粒子天体物理学和宇宙学：过去十年中最活跃的研究领域之一一直是粒子物理学和宇宙学之间的界面。为了了解宇宙的历史，我们必须在大爆炸的第一刻内了解物理定律，而温度和粒子能量很大。相反，通过对当今宇宙的详细观察，我们可以追溯条件，并在高能量下对物理定律进行推论。我们的研究将解决有关宇宙的大问题：为什么比反物质还要多？中微子和暗物质的本质是什么？我们可以使用引力波来查看宇宙的第一秒钟吗？如何使用新的量子技术来搜索暗物质和其他看不见的粒子？量子理论和重力如何结合在一起，我们能在宇宙中看到它们的关节效应？量子场理论的固定点：最近发现，标准模型样理论可以是基本的，并且可以预测到最高能量，而无需渐近地散布，这使一扇门敞开了门。这些新颖的理论提供了紫外线完成标准模型的替代方法，并从全新的角度应对其开放挑战。我们的研究将集中于对这些新类型理论的系统评估，包括超出标准模型的基准模型的构建。我们将这些研究与对量子相对论的量子版本的持续追求相结合。这些场景的预测将与粒子山脉和宇宙学的数据形成对比。高能物理学的工具：高亮度LHC（HL-LHC）被宣布为欧洲粒子物理策略的首要任务，并将在接下来的十年中占主导地位。该科学领域的目的是改善与现象学相关的BSM方案的工具，以便满足HL-LHC的需求。
