摘要:

两个紧凑的普适额外维模型是一类有趣的模型,用于不同的理论和唯象问题,如有三个标准模型费米子家族的理由,质子衰变率的抑制,暗物质宇称来自6维洛伦兹对称的遗迹,质量的起源和混合在标准模型。然而,这些理论仅仅是有效的,通常在其能量范围内有效性范围缩小。我们探讨了两个极限情况下的三个标准模型代都在批量或所有本地化到膜传播,从重整化群方程的角度来看,这些模型的希格斯部门和中微子部门的演变。最近从大型强子对撞机得到的希格斯玻色子玻色子的实验结果,在某些情况下,允许对截止尺度施加更强的限制,这是因为希格斯势的稳定性要求。

英文摘要:

Two compact universal extra dimensional models are an interesting class of models for different theoretical and phenomenological issues, such as the justification of having three standard model fermion families, suppression of proton decay rate, dark matter parity from relics of the 6-dimensional Lorentz symmetry, origin of masses and mixings in the standard model. However, these theories are merely effective ones, with typically a reduced range of validity in their energy scale. We explore two limiting cases of the three standard model generations all propagating in the bulk or all localised to a brane, from the point of view of renormalisation group equation evolutions for the Higgs sector and for the neutrino sector of these models. The recent experimental results of the Higgs boson from the LHC allow, in some scenarios, stronger constraints on the cut-off scale to be placed, from the requirement of the stability of the Higgs potential.
