论文摘要
我们探索了宇宙学效应的测量潜力，例如通过宇宙中微子中微子在triTium上捕获中微子的中微子去耦和中微子聚类的中微子畸变和中微子聚类。我们计算每个中微子物种的精确捕获率，包括这种宇宙学效应以探测它们。这些对捕获率的确切估计值也很重要，因为估计捕获率的可能偏差可能表明宇宙的新中微子物理和/或非标准演变。此外，我们讨论了每种物种的狄拉克和主要中微子的捕获率之间的确切差异，检测每个中微子物种的所需能量分辨率以及通过发射电子光谱重建宇宙中微子的重建方法，并重点介绍了托勒密实验。
We explore the potential of measurements of cosmological effects, such as neutrino spectral distortions from the neutrino decoupling and neutrino clustering in our Galaxy, via cosmic neutrino capture on tritium. We compute the precise capture rates of each neutrino species including such cosmological effects to probe them. These precise estimates of capture rates are also important in that the would-be deviation of the estimated capture rate could suggest new neutrino physics and/or a non-standard evolution of the universe. In addition, we discuss the precise differences between the capture rates of Dirac and Majorana neutrinos for each species, the required energy resolutions to detect each neutrino species and the method of reconstruction of the spectrum of cosmic neutrinos via the spectrum of emitted electrons, with emphasis on the PTOLEMY experiment.
