Holographic Gauge Mediation

Francesco Benini, Anatoly Dymarsky, Sebastian Franco, Shamit Kachru, Dusan Simic, Herman Verlinde

摘要:

我们讨论的引力背景下,超对称性是打破了一个扭曲的喉咙,和超对称性破缺传输到标准模型通过gauginos生活在(部分)的大部分喉几何。我们发现主导效应来自于某些“信使介子”的分裂,它们是支持标准模型规范群的D膜的伴随KK模。这幅图是强耦合场论的引力对偶,其中超对称性在一个隐藏的扇区中被打破,并通过半直接规范中介的相对传递到标准模型。

英文摘要:

We discuss gravitational backgrounds where supersymmetry is broken at the end of a warped throat, and the SUSY-breaking is transmitted to the Standard Model via gauginos which live in (part of) the bulk of the throat geometry. We find that the leading effect arises from splittings of certain "messenger mesons," which are adjoint KK-modes of the D-branes supporting the Standard Model gauge group. This picture is a gravity dual of a strongly coupled field theory where SUSY is broken in a hidden sector and transmitted to the Standard Model via a relative of semi-direct gauge mediation.
