Scalar neutrino dark matter in the blmssm
WebThe BLMSSM is an extension of the minimal supersymmetric standard model (MSSM). Its local gauge group is . Supposing the lightest scalar neutrino is a dark matter candidate, we study the relic density and the spin independent cross section of sneutrino scattering off a nucleon. We calculate the numerical results in detail and find a suitable parameter space. WebAug 30, 2024 · We discuss the connection between the origin of neutrino masses and the properties of dark matter candidates in the context of gauge extensions of the Standard Model. We investigate minimal gauge theories for neutrino masses where the neutrinos are predicted to be Dirac or Majorana fermions. We find that the upper bound on the effective …
