AI总结:

本文详细阐述了杂化M理论中计算模势能的数学与计算方法,将其应用于现实的$B-L$ MSSM模型,成功将dilaton和通用模完全稳定,并证明该真空满足所有Swampland猜想与$Λ$CDM宇宙学约束。

摘要:

我们最近描述了一种在杂化M理论中计算dilaton、复结构和Kähler模势能的协议。这包括在假设包含嵌入$E_8$的异常U(1)结构群的隐藏扇区下,对复结构的领先阶非微扰贡献、gaugino凝聚和worldsheet瞬子。在本文中,我们详细阐明了使用该协议所需的数学和计算方法。然后将这些方法应用于现实的杂化M理论模型,即$B-L$ MSSM,其可观测扇区符合所有粒子物理要求。在此背景下,证明了dilaton和通用模可以完全稳定在与每个唯象学和数学约束以及$Λ$CDM宇宙学相容的值。我们还表明,杂化M理论真空与基于弦理论和量子引力考虑的所有得到充分支持的Swampland猜想一致,并讨论了暗能量定理对紧化理论的含义。

英文摘要:

We recently described a protocol for computing the potential energy in heterotic M-theory for the dilaton, complex structure and Kähler moduli. This included the leading order non-perturbative contributions to the complex structure, gaugino condensation and worldsheet instantons assuming a hidden sector that contains an anomalous U(1) structure group embedded in $E_8$. In this paper, we elucidate, in detail, the mathematical and computational methods required to utilize this protocol. These methods are then applied to a realistic heterotic M-theory model, the $B-L$ MSSM, whose observable sector is consistent with all particle physics requirements. Within this context, it is shown that the dilaton and universal moduli can be completely stabilized at values compatible with every phenomenological and mathematical constraint -- as well as with $Λ$CDM cosmology. We also show that the heterotic M-theory vacua are consistent with all well-supported Swampland conjectures based on considerations of string theory and quantum gravity, and we discuss the implications of dark energy theorems for compactified theories.
