论文摘要
我们提出了一种新的机制，该机制适应弦理论，一种稳定模量的扰动方法，而无需离开扰动控制的领域，从而避免了“用餐见证”问题。唯一必需的非驱动信息来自领先对数的标准重量化组重新召集，这使我们同时在扰动参数$α$中同时工作固定订单，以及$α\lnτ$中的所有订单，其中$τ$是$τ$的大型外量化模量。对于$τ\ sim e^{1/α} $的订单模量自然可以最小化所产生的电势，因此可以给定$ {\ cal o}（10）$输入参数呈指数级。该机制依赖于意外的低能缩放比例对称性，因此对紫外线细节也很强。所得的压缩通常会破坏超对称性，而4D DE Sitter溶液相对容易实现，而无需额外的升高。主题的变化导致通货膨胀情景，稳定模量的大小在通货膨胀之前和之后有很大差异，因此提供了一种动力学机制，使通货膨胀量比晚期的身体（例如$ $ $〜$〜超对称性破坏）的量表大得多，并且在过去的宇宙范围内呈现出稳定的范围，而在宇宙中的范围则是静止的，而效果则是静止的晚期作用。我们将这种形式主义应用于扭曲的$ \ hbox {d3} $ - $ \叠加{\ hbox {d3}} $使用非线性实现的超对称性来描述抗纤维的张力和库仑的交互，并显示出我们的效果稳定性的方式，通常会以$η$ -prorue unbore $ -progro evial evial evial evial evial nevial $ -prodra $ -prodra $ -prodra。我们推测形式主义与在brane-抗内灭绝的后期阶段的tachyon凝结的相关性。
We propose a new mechanism that adapts to string theory a perturbative method for stabilizing moduli without leaving the domain of perturbative control, thereby evading the `Dine-Seiberg' problem. The only required nonperturbative information comes from the standard renormalization-group resummation of leading logarithms that allow us simultaneously to work to a fixed order in the perturbative parameter $α$ and to all orders in $α\lnτ$ where $τ$ is a large extra-dimensional modulus. The resulting potential is naturally minimized for moduli of order $τ\sim e^{1/α}$ and so can be exponentially large given ${\cal O}(10)$ input parameters. The mechanism relies on accidental low-energy scaling symmetries known to be generic and so is robust against UV details. The resulting compactifications generically break supersymmetry and 4D de Sitter solutions are relatively easy to achieve without additional uplifting. Variations on the theme lead to inflationary scenarios for which the size of the stabilized moduli differ significantly before and after inflation and so provide a dynamical mechanism whereby inflationary scales are much larger than late-time physical ($e.g.$~supersymmetry breaking) scales, with this hierarchy contingent on past cosmic evolution with the inflaton playing a secondary late-time role as a relaxation field. We apply this formalism to warped $\hbox{D3}$-$\overline{\hbox{D3}}$ inflation using non-linearly realized supersymmetry to describe the antibrane tension and the Coulomb interaction, and show how doing so our perturbative modulus stabilization mechanism evades the $η$-problem that usually plagues this scenario. We speculate about the relevance of our formalism to tachyon condensation at later stages of brane-antibrane annihilation.
