我们报道了在10−5和10−2电子伏特的质量范围内、混合参数大于10−7的情况下，与假设的隐藏扇区邻子混合的光学波长光子的搜索的第一个结果。这是一个使用“光穿墙照射”技术的生成-再生实验，在该技术中，再生的光子被搜索到将其与上游生成区分开的光障的下游。这里给出的新限制是迄今为止对混合参数最严格的限制。目前的结果表明，在所研究的参数范围内没有光子-邻光子混合的证据。
We report on the first results of a search for optical-wavelength photons mixing with hypothetical hidden-sector paraphotons in the mass range between 10−5and 10−2electron volts for a mixing parameter greater than 10−7. This was a generation-regeneration experiment using the “light shining through a wall” technique in which regenerated photons are searched for downstream of an optical barrier that separates it from an upstream generation region. The new limits presented here are the most stringent limits to date on the mixing parameter. The present results indicate no evidence for photon-paraphoton mixing for the range of parameters investigated.
