Supersymmetric left-right models: LHC-phenomenology, parameter determination and model discrimination

随着大型强子对撞机的开始，对TeV尺度的探索已经开始，人们期待着对物质、力和时空的基本结构有新的见解。此外，预计大型强子对撞机将发现超越粒子物理标准模型(SM)的新物理。SM最有动机的扩展之一是超对称模型，它基于玻色子和费米子之间的对称性。目前的数据表明，任何SM扩展都应该具有关于额外的味道来源和额外的CP违规来源的特殊结构。例如，这可以在基于规范群SU(2)L x SU(2)R x U(1)B-L的超对称模型中实现。这个研究方案的中心议题是研究这样的模型，其中SU(2)RxU(1)B-L破缺发生在TeV范围内，预测了最小超对称标准模型之外的附加态。第一个目标是在大型强子对撞机上探索这些模型的现象学，并找到可以用来确定潜在模型的签名。第二个目标是通过将大型强子对撞机数据与互补实验的数据相结合来确定基本参数，并执行连贯的全球数据分析。应建立公共计算机程序库，供其他合作机构用于相关调查。

With the start of the LHC the exploration of the TeV scale has begun and new insights into the fundamental structure of matter, forces and space-time are expected. Moreover, it is expected that LHC will find new physics beyond the Standard Model (SM) of particle physics. One of the best motivated extensions of the SM are supersymmetric models, which are based on a symmetry relating bosons and fermions. Current data suggests that any SM extension should have a special structure with respect to additional flavour sources and additional sources for CP-violation. This can be for example achieved in supersymmetric models based on the gauge group SU(2)L x SU(2)R x U(1)B-L. The central topic of this research proposal is the investigation of such models where the SU(2)R x U(1)B-L breaking occurs at the TeV ranges predicting additional states beyond the Minimal Supersymmetric Standard Model. The first goal is to explore the phenomenology of these models at the LHC and to find signatures which can be used to pin down the underlying model. The second goal is to determine the underlying parameters by combining LHC data with data from complementary experiments and to perform coherent global data analyses. A public library of computer programs shall be created which can also be used by other collaborations for related investigations.
