论文摘要
本文讨论了包括抗D3-/D7-branes在内的模型构建场景,其中超对称性是自发折断的,尽管没有出现斑点和标准超对称性的规模。如果将麸皮放在卡拉比远的牙齿牙齿尖端的奇异点上,则它们可能会产生逼真的粒子光谱,封闭式和开放式串线模量稳定,并具有Minkowski/de Sitter上升器,以及用于规模层次结构的地球构造起源。该论文为这种情况提供了低能的有效现场理论描述,即标准和受约束的超级典型的非线性超级强烈理论,包括软超对称性物质耦合。闭合弦模量稳定对开弦物质部门的影响,结合了非扰动和扰动效应,并计算出质量和耦合层次结构,以对现象学的看法。
This article discusses model-building scenarios including anti-D3-/D7-branes, in which supersymmetry is broken spontaneously, despite having no scale at which sparticles appear and standard supersymmetry is restored. If the branes are placed on singularities at the tip of warped throats in Calabi-Yau orientifold flux compactifications, they may give rise to realistic particle spectra, closed- and open-string moduli stabilisation with a Minkowski/de Sitter uplift, and a geometrical origin for the scale hierarchies. The paper derives the low-energy effective field theory description for such scenarios, i.e. a non-linear supergravity theory for standard and constrained supermultiplets, including soft supersymmetry-breaking matter couplings. The effect of closed-string moduli stabilisation on the open-string matter sector is worked out, incorporating non-perturbative and perturbative effects, and the mass and coupling hierarchies are computed with a view towards phenomenology.
