中微子振荡已经成为众所周知的现象;中微子混合角和质量平方差的测量正在不断改进。未来的振荡实验将最终确定剩余的未知中微子参数，即质量排序，正常或倒置，和CP破坏阶段。另一方面，中微子的绝对质量尺度可以通过宇宙学观测、单β衰变以及无中微子双β衰变实验来探测。此外，最后一个可以揭示中微子的性质，狄拉克或马约拉纳，通过测量中微子的有效马约拉纳质量。然而，中微子质量产生的机制仍然未知。在中微子领域，一个寻找新物理学的动机很好的唯象方法是非标准相互作用。在这篇简短的评论中，讨论了这幅图中的当前限制因素以及未来实验的前景。
Neutrino oscillations have become well-known phenomena; the measurements of neutrino mixing angles and mass squared differences are continuously improving. Future oscillation experiments will eventually determine the remaining unknown neutrino parameters, namely, the mass ordering, normal or inverted, and the CP-violating phase. On the other hand, the absolute mass scale of neutrinos could be probed by cosmological observations, single beta decay as well as by neutrinoless double beta decay experiments. Furthermore, the last one may shed light on the nature of neutrinos, Dirac or Majorana, by measuring the effective Majorana mass of neutrinos. However, the neutrino mass generation mechanism remains unknown. A well-motivated phenomenological approach to search for new physics, in the neutrino sector, is that of non-standard interactions. In this short review, the current constraints in this picture, as well as the perspectives from future experiments, are discussed.
