摘要:

我们使用专用的隐藏光子探测器在eV能量范围内搜索太阳隐藏光子。探测器由一个直径为500 mm、焦距为1007 mm的抛物柱面镜和一个位于其焦点的光电倍增管组成。该探测器连接到东京轴子日光镜,Sumico,它有一个跟踪太阳的机制。根据测量结果,我们没有发现隐藏光子存在的证据,并根据隐藏光子质量m_{γ'}对光子-隐藏光子混合参数χ设定了一个限制。

英文摘要:

We have searched for solar hidden photons in the eV energy range using a dedicated hidden photon detector. The detector consisted of a parabolic mirror with a diameter of 500mm and a focal length of 1007mm installed in a vacuum chamber, and a photomultiplier tube at its focal point. The detector was attached to the Tokyo axion helioscope, Sumico which has a mechanism to track the sun. From the result of the measurement, we found no evidence for the existence of hidden photons and set a limit on the photon-hidden photon mixing parameter χdepending on the hidden photon mass m_{γ'}.
