Neutrinos in the simplest little Higgs scenario and TeV leptogenesis
  The little Higgs scenario may provide an interesting framework to accommodate TeV scale leptogenesis because a TeV Majorana mass of the right-handed neutrino that we employ for the latter may find a natural place near the ultraviolet cutoff of the former. In this work we study how a light neutrino spectrum, generated radiatively, and TeV scale leptogenesis can be embedded in the simplest little   Higgs framework. Alternatively, we highlight how the neutrino Yukawa textures of the latter are constrained.
