Abstract

In this talk we review the minimal embedding in \(\mathcal{N} = 2\), \(D = 5\) supergravity of a five–dimensional dilaton–gravity theory that serves as a toy model for the holographic dual of six–dimensional little string theory. Interestingly, the toy model also arises in the continuum version of the clockwork mechanism that was recently proposed as a means of addressing the hierarchy problem in a new way. Via a \(U(1)\) gauging that can account for the dilaton potential, it turns out that the linear dilaton background that is present in the holographic dual induces partial supersymmetry breaking in the supergravity theory.

线性Dilaton：从发条机构到超重力嵌入

摘要

在本次演讲中，我们回顾了五维Dilaton-重力理论的最小嵌入\（\ mathcal {N} = 2 \），\（D = 5 \）超重力的情况，该理论用作六个全息全息对偶的玩具模型–维小弦理论。有趣的是，玩具模型也出现在钟表机构的连续版本中，该版本最近被提出来以一种新的方式解决层次问题。通过可以解释Dilaton势的\（U（1）\）度量，事实证明，全息双偶中存在的线性Dilaton背景在超重力理论中引起了部分超对称破坏。
