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.

在过去的两年里，理论物理学和实验物理学携手并进，取得了重大胜利。最终在大型强子对撞机（LHC）上发现了一种类似标准模型的希格斯玻色子。粒子物理学的标准模型现已得到实验证实，包括强、电弱扇区和风味物理。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。我的工作集中在超对称（通过引入一种新的对称性，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进行可能的解释）和扭曲空间的额外维度模型（通过扩展时空的维度，对层次问题进行另一种解释），这是超越标准模型的物理学中最有希望的两种可能性。我计划在非最小的场景下工作（包含额外的粒子和规范对称），这回答了最小版本未解决的一些问题。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相一致。目标是在更高能量和亮度的大型对撞机运行的下一阶段预测新的信号，并在拟议的线性对撞机上，同时保持开放的心态，探索大型对撞机在下一次运行中可能揭示的其他任何东西。
