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. ****This research into beyond the Standard Model will shed some light on the fundamental structure of matter, for both baryonic and dark matter, and the interplay between them. I hope to be able to rule out some possibilities for Physics scenarios beyond the Standard Model, while also indicating promising directions for further explorations.**

过去两年见证了理论物理学和实验物理学携手并进的重大胜利。最终在大型强子对撞机（LHC）中发现了类似标准模型的希格斯玻色子。 粒子物理的标准模型现已通过实验得到证实，包括强物理、弱电扇区和风味物理。虽然大型强子对撞机没有提供其他新物理学的线索，但需要超越标准模型的物理学来解释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波动的起源。我的工作集中于超对称性（通过引入新的对称性，将费米子和玻色子联系起来，对引力尺度和弱尺度之间的层次结构进行可能的解释）和扭曲空间额外维度模型（通过扩展时空维度对层次结构问题的另一种解释），这是标准模型之外最有希望的两种物理学可能性。我计划在非最小场景（包含额外的粒子和规范对称性）中工作，这回答了最小版本未解决的一些问题。 这些模型需要与当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。目标是预测具有更高能量和亮度的大型对撞机操作的下一阶段以及拟议的线性对撞机的新信号，同时保持开放的心态并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息。 ****这项超越标准模型的研究将揭示物质的基本结构，包括重子物质和暗物质，以及它们之间的相互作用。我希望能够排除标准模型之外的物理场景的一些可能性，同时也指出进一步探索的有希望的方向。**
