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.

这项拟议中的研究加入了苏塞克斯、皇家霍洛威和伦敦大学学院伦敦粒子理论小组的科学家们，在四个大标题下寻找新的物理学：对撞机和低能现象学：大型强子对撞机将基本粒子的速度提高到如此接近光速，以至于它们的有效质量增加了十亿倍。通过将这些粒子碰撞在一起，将会有新的发现，新的物理理论将会得到检验。我们将致力于将这些碰撞的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--质量的起源是什么？有引力的量子理论吗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，我们必须了解大爆炸最初时刻的物理定律，当时温度和粒子能量都很大。相反，通过对今天宇宙的详细观察，我们可以追溯到当时的条件，并对高能下的物理定律进行推论。我们的研究将解决有关宇宙的大问题：为什么物质比反物质多？中微子和暗物质的本质是什么？我们能用引力波来观察宇宙的第一皮秒吗？新的量子技术如何用于寻找暗物质和其他不可见粒子？量子理论和引力如何结合，我们能在宇宙中看到它们的联合效应吗？量子场论的不动点：最近发现，标准模型类理论可以是基本的和预测的最高能量，而不是渐近自由，这为未知领域打开了一扇大门。这些新的理论提供了替代方法来UV完成标准模型，并从一个全新的角度来解决其开放的挑战。我们的研究将集中在这些新类型的理论的系统评估，包括标准模型之外的基准模型的建设。我们将联合收割机这些研究与我们对广义相对论量子版本的持续探索相结合。高能物理学的工具：高亮度LHC（HL-LHC）被宣布为欧洲粒子物理学战略的首要任务，并将在未来十年主导对撞机物理学。这个科学领域的目标是改善与现象学相关的BSM场景的工具，以便满足HL-LHC的需求。
