Right-handed sneutrinos as asymmetric DM and neutrino masses from
  neutrinophilic Higgs bosons
  We consider an extension of the Next-to-Minimal Supersymmetric Standard Model
by three right-handed neutrinos and a pair of neutrinophilic Higgs superfields.
The small neutrino masses arise naturally from a small vacuum expectation value
of the additional Higgs fields (hence without lepton number violation), while
the lightest right-handed sneutrinos can constitute asymmetric Dark Matter. The
right-handed sneutrino and baryon asymmetries are connected through equilibrium
processes in the early universe, explaining the coincidence of the DM and
baryon abundances. We show that particle physics and astrophysical constraints
are satisfied.
