研究了IIB型定向折叠背景下Higgs暴胀中的闭弦模稳定化。在这种设置中，大场暴胀是由移动的D 7-膜的真空能量驱动的。背景源中的虚自对偶（ISD）三形式通量是μ项和大场漂移所必需的单值性，而虚反自对偶（IASD）三形式通量是由模稳定所必需的超势的非微扰贡献所产生的。我们详细分析了膨胀子势的Kähler模量稳定化和反作用。在最近的文献中，我们发现，整合出重Kähler模量导致暴胀子势的受控平坦化。我们量化的通量调谐必要的稳定性，即使在大领域的通货膨胀。此外，我们还研究了超对称稳定的复结构模的反作用和在暴胀子的Kähler度规中的轴对称性。与以前的研究结果相反，这种反作用可以被推到很远的领域空间，如果类似的流量调整在凯勒部门是可能的。这允许一个足够大的跨普朗克场范围来支持暴胀。
We study closed-string moduli stabilization in Higgs-otic inflation in Type IIB orientifold backgrounds with fluxes. In this setup large-field inflation is driven by the vacuum energy of mobile D7-branes. Imaginary selfdual (ISD) three-form fluxes in the background source a μ-term and the necessary monodromy for large field excursions while imaginary anti-selfdual (IASD) three-form fluxes are sourced by non-perturbative contri-butions to the superpotential necessary for moduli stabilization. We analyze Kähler moduli stabilization and backreaction on the inflaton potential in detail. Confirming results in the recent literature, we find that integrating out heavy Kähler moduli leads to a controlled flattening of the inflaton potential. We quantify the flux tuning necessary for stability even during large-field inflation. Moreover, we study the backreaction of supersymmetrically stabilized complex structure moduli and the axio-dilaton in the Kähler metric of the inflaton. Contrary to previous findings, this backreaction can be pushed far out in field space if a similar flux tuning as in the Kähler sector is possible. This allows for a trans-Planckian field range large enough to support inflation.
