广义通量模型中闵可夫斯基真空的完全分类

Complete classification of Minkowski vacua in generalised flux models

Beatriz de Carlos, Adolfo Guarino, Jesus M. Moreno

摘要:

我们提出了一个完整的和系统的分析闵可夫斯基极值的N=1,D=4超重力位从II型orientifold模型是T-对偶不变的,在广义通量的存在下。基于我们以前的工作代数跨越通量,和所谓的不去定理的存在Minkowski和/或德Sitter真空,我们进行了部分解析,部分数值分析的有前途的情况下,以前暗示。我们发现,该模型包含一个快子方向的闵可夫斯基极值。此外,由超引力代数so(3,1)^[2]定义的那些模型也包含完全稳定的闵可夫斯基/德西特极小值。所有的闵可夫斯基解,无论稳定与否,都是在参数空间中的一个或几个模为零或无穷大的点之间插值,即所谓的奇点。最后,我们重新解释我们的结果在IIA型通量模型的语言,以明确显示的贡献不同的潜在能源的极值发现,特别是,完全稳定的Minkowski/de Sitter真空的情况下,需要的存在下的非几何通量。

英文摘要:

We present a complete and systematic analysis of the Minkowski extrema of the N=1, D=4 Supergravity potential obtained from type II orientifold models that are T-duality invariant, in the presence of generalised fluxes. Based on our previous work on algebras spanned by fluxes, and the so-called no-go theorems on the existence of Minkowski and/or de Sitter vacua, we perform a partly analytic, partly numerical analysis of the promising cases previously hinted. We find that the models contain Minkowski extrema with one tachyonic direction. Moreover, those models defined by the Supergravity algebra so(3,1)^2 also contain Minkowski/de Sitter minima that are totally stable. All Minkowski solutions, stable or not, interpolate between points in parameter space where one or several of the moduli go to either zero or infinity, the so-called singular points. We finally reinterpret our results in the language of type IIA flux models, in order to show explicitly the contribution of the different sources of potential energy to the extrema found. In particular, the cases of totally stable Minkowski/de Sitter vacua require of the presence of non-geometric fluxes.
