Query: Review of sterile neutrino searches at very short-baseline reactor
  experiments   Search for New Physics beyond the Standard Model is the main direction in
particle physics nowadays. There are several experimental hints of New Physics.
The most statistically significant (5-6$\sigma$) are the hints of eV mass scale
sterile neutrinos. They come from antineutrino disappearance in reactor
experiments, $\nu_e$ disappearance in experiments with very powerful
radioactive sources, and electron (anti)neutrino appearance in the muon
(anti)neutrino beams. Very important results in this field were obtained in
2021 by the BEST, MicroBooNE, and Neutrino-4 collaborations as well as by
several other experiments. However, the situation is still or maybe even more
controversial. We review these indications of New Physics and prospects for the
next few years with the emphasis on reactor experiments.
