通过非常规干涉仪探测宇宙中微子背景的电荷

Probing Cosmic Neutrino Background Charge via Unconventional Interferometer

Chrisna Setyo Nugroho

AI总结:

本研究提出利用激光干涉实验探测宇宙中微子背景(CNB)与光子相互作用引发的相移,可探测量级为$10^{-18}\,e$至$10^{-17}\,e$的CNB中微子电荷,结果具备较强竞争力。

摘要:

如果中微子携带非零电荷,它们会与光子直接相互作用,这会在光学实验中沿光子路径引发相移。我们提出了一种新思路,利用激光干涉实验探测由宇宙中微子背景(CNB)与光子相互作用诱发的这种相移。研究表明,我们的装置可探测量级为$10^{-18}\,e$到$10^{-17}\,e$的CNB中微子电荷,这一结果与现有实验室实验和天体物理观测给出的中微子电荷上限相比颇具竞争力。

英文摘要:

If neutrinos carry non-zero electric charge, they would interact directly with photons. This would induce a phase shift along the photon path in the optical experiment. We propose a novel idea to detect this phase shift induced by cosmic neutrino background (CNB) and the photon interaction using laser interferometry experiment. We show that our setup can probe the CNB neutrino charge in the order of $10^{-18} \,e- 10^{-17}\, e$. This is quite competitive with the existing upper bound on neutrino charge from both laboratory experiments and astrophysical observations.
