论文摘要
基本互动的标准模型尽管是一种令人难以置信的优雅和成功的理论，但缺乏对一些实验和理论开放问题的解释。有趣的是，这些问题中的许多似乎与该理论的电动对称性破坏部门有关，该理论的动力学仍然未知。重要的问题，例如希格斯玻色子的真实本质是什么，为什么它的质量如此轻，如此接近electroweak仪表玻色子的质量，或者该粒子的性质是否是标准模型中预测的粒子的性质。 LHC是我们揭露这些谜团和向量玻色子散射过程的工具，是访问它们的理想窗口，因为它们被认为是电子对称性破坏部门中新物理学最敏感的可观察物。在本论文中，我们采用有效的电动性手性拉格朗日，带有光希格斯，假设具有强烈相互作用的电子对称性破坏部门，对LHC的矢量玻色子散射过程的现象学进行了模型独立的分析，以提出定量预测，以提出对敏感性的定量预测，以实现超出标准模型场景的敏感性。
The Standard Model of fundamental interactions, albeit an incredibly elegant and successful theory, lacks explanations for some experimental and theoretical open questions. Interestingly, many of these problems seem to be related to the electroweak symmetry breaking sector of the theory, whose dynamical generation is still unknown. Important questions such as what is the true nature of the Higgs boson, why is its mass so light and so close to that of the electroweak gauge bosons or whether the properties of this particle are the ones predicted in the Standard Model remain unanswered. The LHC is our tool to unveil these mysteries and vector boson scattering processes are the perfect window to access them, since they are considered as the most sensitive observables to new physics in the electroweak symmetry breaking sector. In this Thesis we employ the effective electroweak chiral Lagrangian with a light Higgs, which assumes a strongly interacting electroweak symmetry breaking sector, to perform a model independent analysis of the phenomenology of vector boson scattering processes at the LHC as well as to present quantitative predictions for the sensitivity to possible beyond the Standard Model physics scenarios.
