Extension of a radiative neutrino mass model based on a cosmological   view point
  We consider an extension of the radiative neutrino mass model at TeV regions so as to give the origin for inflation of the universe. This extension also gives a consistent explanation for both the origin of baryon number asymmetry and dark matter. A small scalar coupling which plays a crucial role in the neutrino mass generation in the original model may be related to parameters which are control inflation.
