摘要:

研究了标准模型的一类无反常阿贝尔扩张的高能行为。我们专注于模型的现象学特征和使用精确的重正化群方法之间的相互作用。使用当前LHC探测器边缘的参数空间区域作为边界条件,出现了与SO(10)大统一理论(GUT)阈值相关的有趣统一模式。我们强调如何发展的两个阿贝尔因子之间的混合可能提供了一个有价值的工具,以解决候选人的高能量嵌入。新出现的统一方案,然后挑战是微扰,并允许一个稳定的真空。

英文摘要:

We study the high-energy behaviour of a class of anomaly-free abelian extensions of the Standard Model. We focus on the interplay among the phenomenological characterisation of the model and the use of precise renormalisation group methods. Using as boundary conditions regions of the parameter space at the verge of current LHC probe, interesting unification patterns emerge linked to thresholds belonging to a SO(10) grand unification theory (GUT). We stress how the evolution of the mixing between the two abelian factors may provide a valuable tool to address the candidate high-energy embedding. The emerging unification scenarios are then challenged to be perturbative and to allow for a stable vacuum.
