keV neutrino dark matter in a fast expanding universe
We study the possibility of keV neutrino dark matter in the minimal U(1)B−L gauge extension of the standard model where three right handed neutrinos are automatically included due to the requirement of anomaly cancellations. Without considering extra additional particles or symmetries, we consider t...
