Abstract

A bstract We consider various string-loop, warping and curvature corrections that are expected to appear in type IIB moduli stabilisation scenarios. It has recently been argued, in the context of strongly-warped LVS de Sitter vacua, that it is impossible to achieve parametric suppression in all of these corrections simultaneously [1]. We investigate corrections in the context of the recently discovered weakly-warped LVS de Sitter vacua, which represent a distinct branch of solutions in type IIB flux compactifications. The weakly-warped solution is supported by small conifold flux numbers MK ≲ 32, but still requires a large flux contribution to the D3-tadpole, now from the bulk. Warping corrections become less problematic, and some corrections even help to reach the weakly-warped regime of parameter space. Other corrections continue to be dangerous and would require numerical coefficients to be computed — and found to be small — in order not to destroy the consistency of the weakly-warped LVS de Sitter solution. We motivate why this may be possible.
德西特真空——什么时候“副标题更正”真的是副标题?
我们考虑了在IIB型模稳定场景中可能出现的各种弦环、翘曲和曲率修正。最近有人认为,在强翘曲LVS de Sitter真空的背景下,在所有这些修正中同时实现参数抑制是不可能的。我们在最近发现的弱翘曲LVS德西特真空的背景下研究了修正,它代表了IIB型通量紧化的一个独特分支。弱翘曲解由较小的con褶通量数MK > 32支持,但仍然需要对3d蝌蚪体的大通量贡献,现在来自体。翘曲修正变得不那么成问题,一些修正甚至有助于达到参数空间的弱翘曲状态。其他修正仍然是危险的,并且需要计算数值系数-并且发现很小-以便不破坏弱翘曲LVS de Sitter解的一致性。我们激发为什么这是可能的。

期刊介绍: The aim of the Journal of High Energy Physics (JHEP) is to ensure fast and efficient online publication tools to the scientific community, while keeping that community in charge of every aspect of the peer-review and publication process in order to ensure the highest quality standards in the journal. Consequently, the Advisory and Editorial Boards, composed of distinguished, active scientists in the field, jointly establish with the Scientific Director the journal''s scientific policy and ensure the scientific quality of accepted articles. JHEP presently encompasses the following areas of theoretical and experimental physics: Collider Physics Underground and Large Array Physics Quantum Field Theory Gauge Field Theories Symmetries String and Brane Theory General Relativity and Gravitation Supersymmetry Mathematical Methods of Physics Mostly Solvable Models Astroparticles Statistical Field Theories Mostly Weak Interactions Mostly Strong Interactions Quantum Field Theory (phenomenology) Strings and Branes Phenomenological Aspects of Supersymmetry Mostly Strong Interactions (phenomenology).
