Query: Leptonic asymmetry of the sterile neutrino hadronic decays in the nuMSM   We consider the leptonic asymmetry generation in the nuMSM via hadronic
decays of sterile neutrinos at T<<T_{EW}, when the masses of two heavier
sterile neutrinos are between pion mass and 2 GeV. The choice of upper mass
bound is motivated by absence of direct experimental searches for singlet
fermions with greater mass. We carried out computations at zero temperature and
ignored the background effects. Combining constraints of sufficient value of
the leptonic asymmetry for production of dark matter particles, condition for
sterile neutrino to be out of thermal equilibrium and existing experimental
data we conclude that it can be satisfied only for mass of heavier sterile
neutrino in the range 1.4 GeV < M < 2 Gev and only for the case of normal
hierarchy for active neutrino mass.
