Doublet-Singlet Oscillations and Dark Matter Neutrinos
We examine the ‘singlet majoron model’ first introduced by Chikashige, Mohapatra and Peccei as a simple extension of the standard model with massive Majorana neutrinos. We can explain both the solar and the atmospheric neutrino deficits by the oscillations between electroweak doublet and singlet neutrinos without flavor mixing. Furthermore, while some light neutrinos can be the hot dark matter,...
متن کاملSinglet scalar dark matter in noncommutative space
In this paper, we examine the singlet scalar dark matter annihilation to becoming the Standard Model particles in the non-commutative space. In the recent decades, many candidates of dark matter have been offered, but our information about the nature of dark matter is still limited. There are such particle candidates as scalar matetr, fermion, boson, gauge boson, etc.; however, they have nei...
متن کاملSinglet fermionic dark matter
We propose a renormalizable model of a fermionic dark matter by introducing a gauge singlet Dirac fermion and a real singlet scalar. The bridges between the singlet sector and the standard model sector are only the singlet scalar interaction terms with the standard model Higgs field. The singlet fermion couples to the standard model particles through the mixing between the standard model Higgs ...
متن کاملDirac Neutrino Dark Matter
We investigate the possibility that dark matter is made of heavy Dirac neutrinos with mass m ∈ [O(1) GeV– a few TeV] and with suppressed but non-zero coupling to the Standard Model Z as well as a coupling to an additional Z ′ gauge boson. The first part of this paper provides a model-independent analysis for the relic density and direct detection in terms of four main parameters: the mass, the ...
متن کاملInert Doublet Dark Matter with an additional scalar singlet and 125 GeV Higgs Boson
In this work we consider a model for particle dark matter where an extra inert Higgs doublet and an additional scalar singlet is added to the Standard Model (SM) Lagrangian. The dark matter candidate is obtained from only the inert doublet. The stability of this one component dark matter is ensured by imposing a Z2 symmetry on this additional inert doublet. The additional singlet scalar has a v...
