The proposed research joins scientists of the particle theory groups at Sussex, Royal Holloway and University CollegeLondon in the hunt for new physics under four broad headings:Collider and low-energy phenomenology:Particle collisions at the energy frontier, presented by the Large Hadron Collider, allow to produce or rule out conjectured new particles thousands of times as heavy as the proton. At intensity frontier, extremely precise measurements of particle interactions allow to probe for even heavier particles in an indirect fashion. Here we explore and combine both directions to unravel the structure of the world at smaller distances than ever, asking questions such as: what makes the known particles so much lighter than the Planck mass of quantum gravity? Is there a unified theory of matter and forces? And how can we best use present and future experiments to shine light on them?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 withoutbeing asymptotically free has opened a door into uncharted territory. These novel theories offer alternative ways to UVcomplete the Standard Model and to address its open challenges from an entirely new angle. Our research will focus onthe systematic evaluation of these new types of theories, including the construction of benchmark models beyond theStandard 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.

拟议的研究加入了苏塞克斯，皇家霍洛威和大学大学的粒子理论小组的科学家，在四个宽阔的标题下寻找新物理学：对撞机和低能现象学：粒子碰撞在能量前沿，由大型的Hadron Collider提出，可以产生或规定猜测的新粒子（如Proton），构成了新的粒子。在强度边界，对粒子相互作用的极为精确的测量可以以间接方式探测更重的颗粒。在这里，我们探索并结合了两个方向，以比以往任何时候都更小的距离揭开世界的结构，例如：什么使已知的粒子比普朗克的量子重力轻得多？有统一的物质和力量理论吗？我们如何最好地使用当前和将来的实验来照亮它们？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与宇宙学之间的界面。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，我们可以追溯情况下的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的事情要多？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：最近的发现，即标准模型样理论可以是基本的，并且可以预测到最高能量，而无需渐近地散发出最高的无形，这使得进入了未知领域。这些新颖的理论提供了替代标准模型的替代方法，并从全新的角度应对其开放挑战。我们的研究将重点放在对这些新类型理论的系统评估上，包括构建TheStandard模型以外的基准模型。我们将这些研究与对量子相对论的量子版本的持续寻求相结合。这些情况的预测将与粒子界面和宇宙学中的数据形成对比。高能物理学的工具：高亮度LHC（HL-LHC）宣布了欧洲粒子物理学的优先权，并将其作为核心物理学战略的首要性，将在下一项胶水胶体物理学中统治下来。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。
