LHC collider phenomenology of minimal universal extra dimensions

We discuss the collider phenomenology of the model of Minimal Universal Extra Dimensions (MUED) at the Large hadron Collider (LHC). We derive analytical results for all relevant strong pair-production processes of two level 1 Kaluza–Klein partners and use them to validate and correct the existing MUED implementation in the fortran version of the Pythia event generator. We also develop a new implementation of the model in the C++ version of Pythia. We use our implementations in conjunction with the Checkmate package to derive the LHC bounds on MUED from a large number of published experimental analyses from Run 1 at the LHC.

我们探讨了大型强子对撞机（Large Hadron Collider, LHC）上的最小通用额外维度（Minimal Universal Extra Dimensions, MUED）模型的对撞机现象学。我们推导了所有与两个第1能级卡鲁扎-克莱因（Kaluza–Klein）伴子的强相互作用对产生过程相关的解析结果，并利用这些结果验证并修正了Pythia事件生成器的Fortran版本中现有的MUED模型实现。我们还在Pythia事件生成器的C++版本中开发了该模型的全新实现方案。我们将自研的模型实现与Checkmate软件包相结合，基于大型强子对撞机运行1期的大量已发表实验分析结果，推导得到了大型强子对撞机针对MUED模型的实验约束。
