论文摘要
逆triumβ衰变(ITBD)反应,$ν_e + ^3 $ h $ \ to e ^ - + ^3 $ He是一种有希望的实验工具,用于观察早期宇宙中创建的遗物中微子。托勒密实验已选择了该反应以搜索遗物中微子。尽管具有潜力,但尚未观察到任何中微子引起的ITBD反应。我们表明,强烈的$^{51} $ cr放射性中微子源适合首次观察ITBD反应。由于太阳是强烈的电子中微子的另一个来源,因此我们还检查了太阳中微子的ITBD反应速率。基于我们最近关于遗物中微子螺旋性演变的研究,我们进一步介绍了捕获遗物中微子作为中微子质量层次结构的函数的ITBD速率,中微子的狄拉克与主要中微子的主要性质以及最轻的中微子的质量。
The inverse tritium beta decay (ITBD) reaction, $ν_e + ^3$H $\to e^- + ^3$He, is a promising experimental tool for observing relic neutrinos created in the early Universe. This reaction has been selected by the PTOLEMY experiment for the search of relic neutrinos. Despite its potential, the ITBD reaction induced by any sources of neutrinos has yet to be observed. We show that an intense $^{51}$Cr radioactive neutrino source is suitable for observing the ITBD reaction for the first time. As the Sun is another source of intense electron neutrinos, we also examine the ITBD reaction rate from solar neutrinos. Based on our recent studies on the evolution of the helicity of relic neutrinos, we further present the ITBD rate for capturing relic neutrinos as a function of neutrino mass hierarchy, the Dirac versus Majorana nature of neutrino, and the mass of the lightest neutrino.
