回顾了有关低能中微子的一些问题。我们重点关注三个方面 i) 我们表明，通过采用非常低能量（几keV）的电子中微子，可以通过检测低阈值球形气态TPC 的反冲电子来研究中微子消失振荡。在这样一个对小混合角 θ13 敏感的实验中，新颖的特征是振荡长度非常小，以至于完全振荡发生在探测器内部。因此，我们可以准确地确定所有振荡参数，特别是测量或设置 θ13 的良好限制。 ii) 低阈值气体 TPC 探测器还可用于通过利用中性电流相互作用来检测核反冲。因此，这些坚固稳定的探测器可用于超新星中微子探测。 iii) 研究了轻子破坏无中微子双衰变，重点是如何从数据中提取绝对中微子质量。
Some issues regarding low energy neutrinos are reviewed. We focus on three aspects i)We show that by employing very low energy (a few keV) electron neutrinos, neutrino disappearance oscillations can be investigated by detecting recoiling electrons with low threshold spherical gaseous TPC's. In such an experiment, which is sensitive to the small mixing angle θ13, the novel feature is that the oscillation length is so small that the full oscillation takes place inside the detector. Thus one can determine accurately all the oscillation parameters and, in particular, measure or set a good limit on θ13. ii) Low threshold gaseous TPC detectors can also be used in detecting nuclear recoils by exploiting the neutral current interaction. Thus these robust and stable detectors can be employed in supernova neutrino detection. iii) The lepton violating neutrinoless double decay is investigated focusing on how the absolute neutrino mass can be extracted from the data.
