论文摘要
当标准模型被认为是有效的量子场理论时，希格斯玻色子的发现提出了质量“轻度”的问题。超对称性是唯一可以保护希格斯质量的当前已知对称性，同时仍将希格斯视为基本量子场。然而，从直接（LHC）和间接搜索（味道，暗物质）的无效搜索（Supersymmetrictric颗粒）和Higgs质量的约束的情况下，已经提出了一些超对称伴侣的重型光谱。 在本论文中，我们通过考虑将许多隔离的弹药场作为超对称性破裂的载体来研究这些重型光谱的可能起源。我们表明，在这些模型中，“自然”的超对称光谱是可能的，尤其是“连贯”的场景会导致微调低，即使使用较重的超对称频谱，轻度的希格斯诺混合暗物质（la focus Point区域）也是如此。然后，我们在字符串景观的上下文中考虑此模型，在那里，我们使用四种磁通量的Bousso-Polchinski框架来建模Spurions。我们表明，在存在大量通量的情况下，可以将违反的超对称光谱的风味参数“稀释”。 考虑所有数据的可能出现的可能出现的超对称光谱之一是生成分裂（Gensplit）光谱，该光谱允许在前两代人出现违反风味的光谱，这很重。我们在超对称SU（5）和质子衰减的背景下研究了这些频谱。结果非常有趣，并且取决于考虑的质子衰减模式。现在根据中微子的风味进行了最强的绑定P与kνi，并在即将进行的Juno，Dune和Hyper K的领域内带来了参数空间。将讨论这些结果。
The discovery of the Higgs boson raises the question of its "lightness" in mass when the Standard Model is considered as an effective quantum field theory. Supersymmetry is the only currently known symmetry which can protect the Higgs mass while still treating the Higgs as an elementary quantum field. However in the view of null experimental confirmation from both direct (LHC) and indirect searches (flavour, dark matter) of the supersymmetric particles and the constraints from the Higgs mass, several possible heavy spectra for supersymmetric partners have been proposed. In the present thesis, we study the possible origins of these heavy spectra by considering a considering many sequestered spurion fields as carriers of supersymmetry breaking. We show that "natural" supersymmetric spectrum is possible in these models and in particular a "coherent" scenario leads to low fine tuning, light Higgsino mixed dark matter ( a la focus point region) even with heavy supersymmetric spectrum. We then consider this model within the context of string landscape, where we use the Bousso-Polchinski framework of four form fluxes to model the spurions. We show that the flavour violating parameters of supersymmetric spectrum can be "diluted" away in the presence of large number of fluxes. One of the possible supersymmetric spectra which emerges by considering all the data is the generation split (Gensplit) spectrum which allows for flavour violation to be present for the first two generations, which are heavy. We study this spectrum within the context of supersymmetric SU(5) and proton decay. The results are quite interesting and dependent on the proton decay mode considered. The strongest bound p to k νis now modified depending on the flavour of the neutrino and brings the parameter space within the realms of upcoming experiments of JUNO, DUNE and Hyper K. These results will be discussed.
