论文摘要
使用低能量有效的现场理论方法,我们研究了具有较大额外维度的模型的某些特性,其中夸克和舔子在额外的维度中具有局部波函数。我们考虑具有两种类型的量规组的模型:(i)标准模型量规组,以及(ii)左右对称(LRS)仪表组。我们的主要重点是$ n = 2 $额外尺寸的模型的Lepton领域,尤其是中微子质量和混合。我们分析了模型必须满足的必要条件与数据一致,并在满足这些条件的额外维度中为Lepton Wave函数提供了解决方案。作为我们工作的一部分,我们还为夸克波功能中心提供了一个新的解决方案。评估了改变风味的中性电流效应的问题。最后,我们在这些模型中评论了男性生成和暗物质。
Using a low-energy effective field theory approach, we study some properties of models with large extra dimensions, in which quarks and leptons have localized wave functions in the extra dimensions. We consider models with two types of gauge groups: (i) the Standard-Model gauge group, and (ii) the left-right symmetric (LRS) gauge group. Our main focus is on the lepton sector of models with $n=2$ extra dimensions, in particular, neutrino masses and mixing. We analyze the requisite conditions that the models must satisfy to be in accord with data and present a solution for lepton wave functions in the extra dimensions that fulfills these conditions. As part of our work, we also present a new solution for quark wave function centers. Issues with flavor-changing neutral current effects are assessed. Finally, we remark on baryogenesis and dark matter in these models.
