Phenomenological studies of Beyond the Standard Model scenarios

在过去的两年里，理论物理和实验物理携手合作取得了重大胜利。这最终在大型强子对撞机(LHC)上发现了一个类似标准模型的希格斯玻色子。粒子物理的标准模型现已从实验上得到确认，包括强电弱区物理和气味物理。虽然大型强子对撞机没有提供其他新物理学的迹象，但需要超越标准模型的物理学来解释关于中微子质量和混合的实验数据，宇宙学和天体物理学也需要新的物理学来解释物质、暗物质、暗能量和宇宙微波背景涨落的起源。我的工作集中在超对称性(通过引入一种新的对称性，将费米子和玻色子联系起来，可能解释引力标度和弱标度之间的等级)和扭曲空间额外维度模型(通过扩展时空维度，对等级问题的另一种解释)，这是超越标准模型的两种最有希望的物理学可能性。我计划在非最小情况下工作(包含额外的粒子和规范对称性)，它们回答了最小版本留下的一些未解决的问题。这些模型需要与目前的对撞机实验以及直接或间接寻找暗物质的实验保持一致。目标是在大型对撞机运行的下一阶段(S)以更高的能量和亮度预测新信号，并在拟议的线性对撞机上预测新信号，同时保持开放的心态，探索大型强子对撞机在下一次运行中可能揭示的任何其他信号。

The past two years have seen a major triumph of theoretical and experimental physics working hand in hand. This culminated in the discovery of a Standard Model-like Higgs boson at the Large Hadron Collider (LHC). The Standard Model of particle physics is now confirmed experimentally, including strong, electroweak sector and flavour physics. While the Large Hadron Collider has provided no hint of other new physics, Physics beyond the Standard Model is needed to explain experimental data on neutrino masses and mixing, and cosmology and astrophysics also require new physics to explain the origin of matter, dark matter, dark energy and the Cosmic Microwave Background fluctuations. My work concentrates on supersymmetry (a possible explanation of the hierarchy between the gravitational scale and the weak scale by introducing a new symmetry, relating fermions and bosons), and on warped space extra dimensional models (an alternative explanation of the hierarchy problem, by extending the dimensions of space-time), as two of the most promising possibilities of physics beyond the Standard Model. I plan to work in non-minimal scenarios (containing extra particles and gauge symmetries), which answer some of the issues left unresolved by minimal versions. These models are required to be consistent with present collider experiments, and with experiments searching directly or indirectly for dark matter. The goal is to predict new signals at the next phase(s) of the large collider operation with higher energy and luminosity, and at the proposed linear collider, while keeping an open mind and explore whatever else the LHC may reveal in its next run.
