We address the phenomenology of light sterile neutrinos, with emphasis on short-baseline neutrino oscillations. After a review of the observed short-baseline neutrino oscillation anomalies, we discuss the global fit of the data and the current appearance-disappearance tension. We also review briefly the effects of light sterile neutrinos in $\beta$ decay, neutrinoless double-$\beta$ decay and cosmology. Finally, we discuss the future perspective in the search for the effects of eV-scale sterile neutrinos.

eV 级无菌中微子

我们讨论轻惰性中微子的现象学，重点是短基线中微子振荡。在回顾了观察到的短基线中微子振荡异常之后，我们讨论了数据的全局拟合和当前的出现-消失张力。我们还简要回顾了轻惰性中微子在 $\beta$ 衰变、无中微子双 $\beta$ 衰变和宇宙学中的影响。最后，我们讨论了寻找 eV 级无菌中微子影响的未来前景。
