项目摘要

Understanding the physics at the smallest scale and highest energy is one of the major challenges that particle theorists face at present. While we understanding the particles and the interactions at the electroweak scales, theoretical problems remain open. In particular, we do not understand what is the physics beyond the Standard Model which can unify all the known forces. One of the most promising theories is string theory which could be realised at the highest possible energy scales in the Universe or, in the case of extra-dimension models, at the energy regime which is going to be tested by the experiments at the LHC. The aim of this project is to study the possible low energy manifestations of the string theory models, which can give signatures at the LHC, in flavour physics experiments and can have had an impact on the evolution of the Universe. By studying these experimental signals from a theoretical point of view it is possible to extract information the high energy physics and try to identify the ultimate theory beyond the Standard Model. The project will involve complex analytical computations using state of the art mathematical techniques and will resort on numerical study with the aid of computer simulations. The Institute for Particle Physics Phenomenology (IPPP) in Durham, has an outstanding expertise in the theoretical aspects of physics beyond the Standard Model and on its phenomenological signatures and it is an ideal place for this ambitious project.

理解最小尺度和最高能量的物理是粒子理论学家目前面临的主要挑战之一。虽然我们了解了电弱尺度上的粒子和相互作用，但理论问题仍然悬而未决。特别是，我们不明白标准模型之外的物理是什么，它可以统一所有已知的力。最有前途的理论之一是弦理论，它可以在宇宙中尽可能高的能量尺度上实现，或者在超维度模型的情况下，在大型强子对撞机上的实验将测试的能量状态下实现。该项目的目的是研究弦理论模型可能的低能量表现，这些模型可以在大型强子对撞机、味道物理实验中给出特征，并且可以对宇宙的演化产生影响。通过从理论角度研究这些实验信号，可以提取高能物理信息并尝试识别标准模型之外的终极理论。该项目将涉及使用最先进的数学技术进行复杂的分析计算，并将借助计算机模拟进行数值研究。位于达勒姆的粒子物理现象学研究所 (IPPP) 在标准模型之外的物理学理论方面及其现象学特征方面拥有杰出的专业知识，是这个雄心勃勃的项目的理想场所。
