CalcHEP/CompHEP中的极小泛额外维数
Minimal Universal Extra Dimensions in CalcHEP/CompHEP
摘要：
我们提出了一个实现的模型的最小通用额外的尺寸（MUED）在CalcHEP/CompHEP。我们包括希格斯扇区之外的所有1级和2级卡鲁扎-克莱因（KK）粒子。质谱是根据MUED中的两个输入参数在一个循环中自动计算的：额外维度的半径和模型的截止尺度。我们实现了KK粒子的KK数守恒和KK数破坏相互作用。我们还考虑了规范耦合常数在电弱标度以上的正常运行。实施已广泛的交叉检查对已知的分析结果在文献中和其他程序的数值结果。我们的文件是公开的，可用于在MUED模型中执行各种自动计算。
英文摘要：
We present an implementation of the model of minimal universal extra dimensions (MUED) in CalcHEP/CompHEP. We include all level-1 and level-2 Kaluza-Klein (KK) particles outside the Higgs sector. The mass spectrum is automatically calculated at one loop in terms of the two input parameters in MUED: the radius of the extra dimension and the cut-off scale of the model. We implement both the KK number conserving and the KK number violating interactions of the KK particles. We also account for the proper running of the gauge coupling constants above the electroweak scale. The implementation has been extensively cross-checked against known analytical results in the literature and numerical results from other programs. Our files are publicly available and can be used to perform various automated calculations within the MUED model.
