标题： Dynamically Induced Topological Inflation

摘要： 我们提出了一种膨胀模型，在其中膨胀时代由$Sp(2)$规范理论的强动力学驱动。 $Sp(2)$规范理论受限相中的夸克凝聚生成了与相变时热浴能量相当的膨胀子势能。 随后，在超Planck尺度的全局最小值下，膨胀在真真空区域之间的假真空区域开始，因此被称为“拓扑膨胀”。 由于假真空（$V(0)^{1/4}\sim10^{15}{\rm GeV}$）和全局最小值（$\langle\phi\rangle\sim M_{P}$）之间巨大的尺度分离，该模型能够与CMB观测结果一致，而不会受到初始条件问题的影响。 关键的是，这是在不需调整$V(\phi)$参数的情况下实现的。 除了$Sp(2)$之外，该模型还基于无反常的$Z_{6R}$离散$R$对称性。 值得注意的是，尽管所有参数均由宇宙微波背景（CMB）观测固定，但该模型预测了一系列能量尺度，包括暴胀尺度、超对称破缺尺度、R-对称破缺尺度、Higgsino 质量以及以$Sp(2)$的动力学尺度表示的右手中微子质量。 显示英文摘要

摘要： We propose an inflation model in which the inflationary era is driven by the strong dynamics of $Sp(2)$ gauge theory. The quark condensation in the confined phase of $Sp(2)$ gauge theory generates the inflaton potential comparable to the energy of the thermal bath at the time of phase transition. Afterwards, with super-Planckian global minimum, the inflation commences at a false vacuum region lying between true vacuum regions and hence the name "topological inflation". Featured by the huge separation between the scale of the false vacuum ($V(0)^{1/4}\sim10^{15}{\rm GeV}$) and the global minimum ($\langle\phi\rangle\sim M_{P}$), the model can be consistent with CMB observables without suffering from the initial condition problem. Crucially, this is achieved without any fine-tuning of parameters in $V(\phi)$. In addition to $Sp(2)$, this model is based on an anomaly free $Z_{6R}$ discrete $R$ symmetry. Remarkably, while all parameters are fixed by CMB observations, the model predicts a hierarchy of energy scales including the inflation scale, SUSY-breaking scale, R-symmetry breaking scale, Higgsino mass and the right-handed neutrino mass given in terms of the dynamical scale of $Sp(2)$.
