Gaugino凝聚与宇宙学常数

Gaugino Condensation and the Cosmological Constant

Callum Quigley

摘要:

在弦论中,德西特解的存在性受到不通过定理的强约束。我们继续研究杂种优势有效作用的修正,目的是加强或避免这些限制。我们考虑了H通量、规范束、高阶导数修正和高吉诺凝聚的综合效应。在四维空间中,我们发现的唯一具有最大对称性的相容解是闵可夫斯基时空,排除了由这些成分单独构造的德西特解和反德西特解。

英文摘要:

The existence of de Sitter solutions in string theory is strongly constrained by no-go theorems. We continue our investigation of corrections to the heterotic effective action, with the aim of either strengthening or evading the these constraints. We consider the combined effects of H-flux, gauge bundles, higher derivative corrections and gaugino condensation. The only consistent solutions we find with maximal symmetry in four dimensions are Minkowski spacetimes, ruling out both de Sitter and anti-de Sitter solutions constructed from these ingredients alone.
