Chameleon约束概要

A Compendium of Chameleon Constraints

Clare Burrage, Jeremy Sakstein

摘要:

变色龙模型是一个具有屏蔽机制的标量场理论,它解释了宇宙学相关的光标量如何避免太阳系内寻找第五种力的限制。变色龙是一种流行的暗能量候选者,也出现在引力的$f(R)$理论中。虽然变色龙的设计是为了避免历史搜索的第五力,它不是不可观测的,许多努力已经进入确定最好的观测和实验来检测它。这些结果并不总是为相同的模型或相同的语言,一个特殊的问题时,比较天体物理和实验室搜索很难理解哪些区域的参数空间仍然存在。在这里,我们提出了结合约束的变色龙模型从天体物理和实验室搜索的第一次,并确定剩余的窗口参数空间。我们讨论了宇宙学变色龙搜索和未来的小规模探测的影响。

英文摘要:

The chameleon model is a scalar field theory with a screening mechanism that explains how a cosmologically relevant light scalar can avoid the constraints of intra-solar-system searches for fifth-forces. The chameleon is a popular dark energy candidate and also arises in $f(R)$ theories of gravity. Whilst the chameleon is designed to avoid historical searches for fifth-forces it is not unobservable and much effort has gone into identifying the best observables and experiments to detect it. These results are not always presented for the same models or in the same language, a particular problem when comparing astrophysical and laboratory searches making it difficult to understand what regions of parameter space remain. Here we present combined constraints on the chameleon model from astrophysical and laboratory searches for the first time and identify the remaining windows of parameter space. We discuss the implications for cosmological chameleon searches and future small-scale probes.
