Elko as an inflaton candidate
Abstract Elko is a spin-half fermion with a two-fold Wigner degeneracy and Klein–Gordon dynamics. In this paper, we show that in a spatially flat FLRW space-time, slow-roll inflation can be initiated by the homogeneous Elko fields. The inflaton is a composite scalar field obtained by contracting the...
