隔离型通货膨胀

Sequestered Inflation

Renata Kallosh, Andrei Linde, Timm Wrase, Yusuke Yamada

摘要:

我们构建超引力模型,允许隔离从普朗克能量标度物理暴胀的现象。该过程包括两个步骤:在第一步,我们研究超引力模型,这可能与弦论或M-理论,并具有超对称的闵可夫斯基真空与平坦的方向。在第二步,我们将这些平坦方向提升到暴胀平台势。我们找到了某些条件,这些条件确保了在第一步中闵可夫斯基真空稳定化过程中所涉及的超重场与暴胀现象完全解耦。

英文摘要:

We construct supergravity models allowing to sequester the phenomenology of inflation from the Planckian energy scale physics. The procedure consists of two steps: At Step I we study supergravity models, which might be associated with string theory or M-theory, and have supersymmetric Minkowski vacua with flat directions. At Step II we uplift these flat directions to inflationary plateau potentials. We find certain conditions which ensure that the superheavy fields involved in the stabilization of the Minkowski vacua at Step I are completely decoupled from the inflationary phenomenology.
