论文摘要
Supergravity是一种局部超对称规格理论，可以提供以外的标准模型（BSM）以外的新物理学。从这个意义上讲，超级实力的宇宙学应用可能是探测超级重力结果的领域。超级重力可以作为超能量的超级弦理论（可能是量子重力的候选者）出现的，这也很有吸引力。然而，由于困难主要是由于超级严重标量势的极度限制形式，相互作用项的复杂结构和过度的自由度标量，因此，建立超级重力的通货膨胀模型并不是微不足道的。这些障碍物通常使得构成理想的通货膨胀轨迹，执行模量稳定以获得稳定的脱水阶段，并使额外的标量比哈勃尺度更重以获得单场通货膨胀更重。此外，超级实力预测了许多不可降低的相互作用。因此，它是作为有效的现场理论（EFT）而出现的，该理论只能有效，以至于典型的能量$ e $低于其Ultraviolet截止量表$λ_{cut} $，并且我们想要的$（e/λ_{cut}）^n $的准确度（e/λ_{cut}）我们注意到，这些不可分割的术语可能会影响通货膨胀期间和/或之后的物理。从这种角度来看，在超级重力中找到放松标量电势的方法和灵活的标量场动力学（尤其是对于充气量），并在量子水平上检查自符合性，这一点非常重要。因此，在本论文中，我们通过考虑$ \ Mathcal {n} = 1 $超级重力的近期重新制定，构建了本地超对称的有效的通货膨胀的有效领域理论（具有KKLT字符串背景），从而扩大了标量势的空间。
Supergravity, a locally supersymmetric gauge theory, may provide to describe new physics beyond the Standard Model (BSM). In this sense, cosmological applications of supergravity can be the arena for probing outcomes of supergravity. It is also attractive that supergravity can appear as a low-energy effective theory of superstrings, a possible candidate of quantum gravity. Nevertheless, it is not trivial to build inflationary models in supergravity due to difficulties arising mainly from the extremely constrained form of supergravity scalar potentials, complicated structure of interaction terms, and excessive scalar degrees of freedom. These obstructions generally make it challenging to contrive a desirable inflationary trajectory, perform the moduli stabilization to obtain the stable de-Sitter phase, and make extra scalars to be much heavier than the Hubble scale to get single field inflation. Besides, supergravity predicts many non-renormalizable interactions. It thus arises as effective field theory (EFT) which can be valid only up to typical energies $E$ below its ultraviolet cutoff scale $Λ_{cut}$, and up to some accuracy of $(E/Λ_{cut})^n$ that we desire. We note that these non-renormalizable terms may affect physics during and/or after inflation. From such points of view, it is very important in supergravity to find the method for relaxing the scalar potentials, and flexible scalar field dynamics (particularly for inflaton), and examine self-consistency at the quantum level. In this thesis, therefore, we construct locally supersymmetric effective field theories of inflation (with KKLT string background) by taking into account recently-proposed reformulations of $\mathcal{N}=1$ supergravity that can enlarge the space of scalar potentials.
