We report results from a search for chameleon particles created via photon-chameleon oscillations within a magnetic field. This experiment is sensitive to a wide class of unexplored chameleon power-law and dark energy models. These results exclude 5 orders of magnitude in the coupling of chameleons to photons covering a range of 4 orders of magnitude in chameleon effective mass and, for individual models, exclude between 4 and 12 orders of magnitude in chameleon couplings to matter.
我们报告了通过磁场中的光子-变色龙振荡产生的变色龙粒子的搜索结果。该实验对广泛的未探索的变色龙幂律和暗能量模型敏感。这些结果排除了变色龙与光子耦合的 5 个数量级，涵盖了变色龙有效质量的 4 个数量级范围，对于个别模型，排除了变色龙与物质耦合的 4 到 12 个数量级。
