Query: Interpretation of the XENON1T excess in the model with decaying sterile
  neutrinos   The phenomenological model with three active and three sterile neutrinos is
used for interpretation of the observed XENON1T excess of electronic recoil
events in the 1 -- 7 keV energy region. Assuming two sterile neutrinos with
appropriate mass values decay while the third sterile neutrino is stable it is
possible to explain the observed energy spectrum of electronic recoil events.
Moreover using this approach three peaks in the 1 -- 7 keV energy region are
predicted. Dark bosons have to mix to only a small extent with photons which
can be emitted in this region. The possible existence of the three light
sterile neutrinos may have perceptible influence on some phenomena in neutrino
physics, astrophysics and cosmology.
