在Super-Kamiokande中寻找隐藏的扇形光子

On search for hidden sector photons in Super-Kamiokande

S. N. Gninenko

摘要:

如果隐藏扇区光子存在,它们可能是通过太阳发射的光子振荡产生的。我们表明,这些粒子的搜索可以在超级神冈由于在这个检测器中的大量的光电倍增管(PMT)的存在下进行,具有相对低的噪声和大尺寸。这些粒子将穿透地球屏蔽层,并通过它们在PMT真空体积内振荡成真实光子而被PMT检测到。这将导致PMT计数率的增加,并且其每日变化取决于地球相对于太阳的位置。对于隐光子质量范围~10^{-3} - 10^{-1} eV,所提出的对这种效应的研究对小到~10 ^{-6}的光子-隐光子混合强度是敏感的,并且在没有观测的情况下,可以改善最近从光子再生激光实验中获得的该质量范围的限制。

英文摘要:

If hidden sector photons exist, they could be produced through oscillations of photons emitted by the Sun. We show that a search for these particles could be performed in Super-Kamiokande due to the presence in this detector of a large number of photomultiplier's (PMTs) with a relatively low noise and big size. These particles would penetrate the Earth shielding and would be detected by PMTs through their oscillations into real photons inside the PMTs vacuum volume. This would results in an increase of the PMT counting rate and it daily variations depending on the Earth position with respect to the Sun. The proposed search for this effect is sensitive to the photon-hidden photon mixing strength as small as ~10^{-6} for the hidden photon mass region ~10^{-3} - 10^{-1} eV and, in the case of nonobservation, could improve limits recently obtained from photon regeneration laser experiments for this mass region.
