Description
An extension of the Standard Model by three singlet fermions with
masses smaller than the electroweak scale allows to explain
simultaneously neutrino oscillations, dark matter and baryon
asymmetry of the Universe. We discuss here the properties of
neutral leptons in this model and the ways they can be searched
for in particle physics experiments. In particular, if sterile
neutrinos are lighter than kaons, they can be produced in
leptonic and semileptonic kaon decays with branching ratios only
one-two orders of magnitude below the current experimental limits
from direct searches. This gives a unique possibility to either
prove or rule out nuMSM with light sterile neutrinos.
