We investigate the viability of having dark matter in the minimal left-right symmetric theory. We find the lightest right-handed neutrino with a mass around keV as the only viable candidate consistent with a TeV scale of left-right symmetry. In order to account for the correct relic density with such low scales, the thermal overproduction of the dark matter in the early universe is compensated by a sufficient late entropy production due to late decay of heavier right-handed neutrinos. We point… Expand

Prospects of gravitational waves in the minimal left-right symmetric model
The left-right symmetric model (LRSM) is a well-motivated framework to restore parity and implement seesaw mechanisms for the tiny neutrino masses at or above the TeV-scale, and has a very richExpand

Sterile neutrinos as dark matter.
TLDR
This model is reexamine and it is found that hot, warm, and cold dark matter are all possibilities and the number density of sterile neutrinos is proportional to [mu][sup 2]/M so that the energy density today is independent of M, which is crucial in determining the large scale structure of the Universe.
