Fourth Generations with an Inert Doublet Higgs
Efunwande Osoba
We explore an extension of the fourth generation model with multi-Higgs doublets and three fermion singlets. The Standard Model neutrinos acquire mass radiatively at one loop level…
Inert-Sterile Neutrino: Cold or Warm Dark Matter Candidate
Graciela B. Gelmini, Efunwande Osoba, Sergio Palomares-Ruiz
In usual particle models, sterile neutrinos can account for the dark matter of the Universe only if they have masses in the keV range and are warm dark matter. Stringent cosmologic…
MeV sterile neutrinos in low reheating temperature cosmological scenarios
Graciela Gelmini, Efunwande Osoba, Sergio Palomares-Ruiz +1
It is commonly assumed that the cosmological and astrophysical bounds on the mixings of sterile with active neutrinos are much more stringent than those obtained from laboratory me…
