Double type-II Dirac seesaw accompanied by Dirac fermionic dark matter
نویسندگان
چکیده
A TeV-scale Higgs doublet with a small mixing to the standard model can have sizable Yukawa couplings several right-handed neutrinos and lepton doublets. This provides testable Dirac neutrino mass generation. We further consider seesaw mechanism involving $U(1)_{B-L}^{}$ gauge symmetry, which predicts existence of two stable fermionic dark matter, simultaneously explain between doublets generation cosmic baryon asymmetry.

Dirac 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 کاملPseudo-Dirac dark matter leaves a trace.
Pseudo-Dirac dark matter is a viable type of dark matter which originates from a new Dirac fermion whose two Weyl states get slightly split in mass by a small Majorana term. The decay of the heavier to the lighter state naturally occurs over a detectable length scale. Thus, whenever pseudo-Dirac dark matter is produced in a collider, it leaves a clear trace: a visible displaced vertex in associ...
متن کاملAn Effective Theory of Dirac Dark Matter
A stable Dirac fermion with four-fermion interactions to leptons suppressed by a scale Λ ∼ 1 TeV is shown to provide a viable candidate for dark matter. The thermal relic abundance matches cosmology, while nuclear recoil direct detection bounds are automatically avoided in the absence of (large) couplings to quarks. The annihilation cross section in the early Universe is the same as the annihil...

متن کاملMinimal dark matter in type III seesaw
We explore the possibility of a new dark matter candidate in the supersymmetric type III seesaw mechanism where a neutral scalar component of the Y= 0 triplet can be the lightest supersymmetric particle. Its thermal abundance can be in the right range if non-standard cosmology such as kination domination is assumed. The enhanced cross-section of the dark matter annihilation to WW can leave dete...
