变色龙式日光镜
A chameleon helioscope
摘要：
可以解释暗能量的变色龙粒子在许多方面与轴子相似，这表明轴子日光镜可以用于变色龙探测。与标准模型粒子不同的是，变色龙粒子的有效质量取决于周围物质的能量密度。相关的全内反射的变色龙高达keV的能量由一个致密的材料层，这将发生在掠入射的X射线望远镜的镜子，导致新的实验技术来检测这样的粒子。我们在这里讨论这种全内反射何时发生，以及如何在现有或未来最先进的变色龙望远镜中实现。太阳变色龙主要以低于几keV的能量发射，这表明X射线望远镜是变色龙复制的基本组件。这一想法的实施是直截了当的，但值得进一步审查。结合现有设备准备和运行一个暗能量候选粒子探测实验似乎很有希望。例如，大体积和强螺线管磁场，这是不适合太阳轴子调查，是有吸引力的变色龙复制的观点。
英文摘要：
Chameleon particles, which could explain dark energy, are in many ways similar to axions, suggesting that an axion helioscope can be used for chameleon detection. The distinguishing property of chameleon particles is that, unlike Standard Model particles, their effective masses depend upon the ambient matter-energy density. The associated total internal reflection of chameleons up to keV energies by a dense layer of material, which would occur at grazing incidence on the mirrors of an X-ray telescope, lead to new experimental techniques for detecting such particles. We discuss here when this total internal reflection can happen and how it can be implemented in existing or future state-of-the-art chameleon telescopes. Solar Chameleons would be emitted mainly with energies below a few keV suggesting the X-ray telescope as the basic component in chameleon telescopy. The implementation of this idea is straightforward, but it deserves further scrutiny. It seems promising to prepare and run a dark energy particle candidate detection experiment combining existing equipment. For example, large volumes and strong solenoid magnetic fields, which are not appropriate for solar axion investigations, are attractive from the point of view of chameleon telescopy.
