用冷原子测量中微子质量
Using Cold Atoms to Measure Neutrino Mass
摘要:
我们提出了一个基于超冷原子氚样品的β衰变实验。这些初始条件使氦离子的检测符合β。我们构建了一个二维的拟合,将β-光谱的形状和中微子质量峰的直接重建。我们目前的模拟结果的中微子质量的可行限制,在这种新型的氚β衰变实验中实现。
英文摘要:
We propose a beta decay experiment based on a sample of ultracold atomic tritium. These initial conditions enable detection of the helium ion in coincidence with the beta. We construct a two-dimensional fit incorporating both the shape of the beta-spectrum and the direct reconstruction of the neutrino mass peak. We present simulation results of the feasible limits on the neutrino mass achievable in this new type of tritium beta-decay experiment.
