用M理论解释电弱标度和稳定化模
Explaining the Electroweak Scale and Stabilizing Moduli in M Theory
摘要：
在最近的一篇论文\cite{Acharya:2006ia}中，它表明，在$M$理论真空没有通量，所有的模稳定的有效势和一个稳定的层次产生，符合标准规范统一。本文更详细地解释了\cite{Acharya:2006ia}的结果并推广了它们，在合理的条件下找到了本质上唯一的de Sitter（dS）真空.主要的唯象结果之一是从这整个真空类别中出现的一个预言：即相对于引力子质量，高吉诺质量被显著抑制。我们还提出的证据表明，对于那些真空中的真空能量是小的，引力子的质量，它设置所有的超伙伴质量，是自动在TeV - 100 TeV的范围。
英文摘要：
In a recent paper \cite{Acharya:2006ia} it was shown that in $M$ theory vacua without fluxes, all moduli are stabilized by the effective potential and a stable hierarchy is generated, consistent with standard gauge unification. This paper explains the results of \cite{Acharya:2006ia} in more detail and generalizes them, finding an essentially unique de Sitter (dS) vacuum under reasonable conditions. One of the main phenomenological consequences is a prediction which emerges from this entire class of vacua: namely gaugino masses are significantly suppressed relative to the gravitino mass. We also present evidence that, for those vacua in which the vacuum energy is small, the gravitino mass, which sets all the superpartner masses, is automatically in the TeV - 100 TeV range.
