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.

随着大型强子对撞机的启动，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的新见解。此外，预计LHC将发现超越粒子物理标准模型（SM）的新物理。超对称模型是SM的最佳扩展之一，它基于玻色子和费米子的对称性。目前的数据表明，任何SM扩展应该有一个特殊的结构方面的额外的风味来源和额外的来源CP违规。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。这项研究计划的中心议题是调查这样的模型，其中SU（2）R x U（1）B-L破缺发生在TeV范围内，预测超出最小超对称标准模型的其他状态。第一个目标是在LHC上探索这些模型的现象学，并找到可用于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补充实验的数据相结合来确定基本参数，并进行连贯的全球数据分析。应建立一个计算机程序的公共图书馆，该图书馆也可供其他合作机构用于相关调查。
