Title: TeV scale leptogenesis, inflaton dark matter, and neutrino mass in a scotogenic model

Abstract

We consider the scotogenic model, where the standard model (SM) is extended by a scalar doublet and three Z₂ odd SM-singlet fermions (N_i, i = 1, 2, 3), all odd under an additional Z₂ symmetry, as a unifying framework for simultaneous explanation of inflation, dark matter, baryogenesis and neutrino mass. The inert doublet is coupled nonminimally to gravity and forms the inflaton. The lightest neutral particle of this doublet later becomes the dark matter candidate. Baryogenesis is achieved via leptogenesis by the decay of N₁ to SM leptons and the inert doublet particles. Neutrino masses are generated at the one-loop level. Explaining all these phenomena together in one model is very economic and gives us a new set of constraints on the model parameters. We calculate the inflationary parameters like spectral index, tensor-to-scalar ratio and scalar power spectrum, and find them to be consistent with the Planck 2018 constraints. We also do the reheating analysis for the inert doublet decays/annihilations to relativistic, SM particles. We find that the observed baryon asymmetry of the Universe can be obtained and the sum of light neutrino mass bound can be satisfied for the lightest Z₂ odd singlet fermion of mass around 10 TeV,more »« less

FIMP realization of the scotogenic model

Journal Article Molinaro, Emiliano ; Zapata, Oscar ; Yaguna, Carlos E., E-mail: emiliano.molinaro@tum.de, E-mail: carlos.yaguna@uni-muenster.de, E-mail: ozapata@fisica.udea.edu.co - Journal of Cosmology and Astroparticle Physics

The scotogenic model is one of the simplest scenarios for physics beyond the Standard Model that can account for neutrino masses and dark matter at the TeV scale. It contains another scalar doublet and three additional singlet fermions (N{sub i}), all odd under a Z{sub 2} symmetry. In this paper, we examine the possibility that the dark matter candidate, N{sub 1}, does not reach thermal equilibrium in the early Universe so that it behaves as a Feebly Interacting Massive Particle (FIMP). In that case, it is found that the freeze-in production of dark matter is entirely dominated by the decaysmore »« less

Model of TeV scale physics for neutrino mass, dark matter, and baryon asymmetry and its phenomenology

Journal Article Aoki, Mayumi ; Kanemura, Shinya ; Seto, Osamu - Physical Review. D, Particles Fields

We discuss some details of the model proposed [M. Aoki, S. Kanemura, and O. Seto, Phys. Rev. Lett. 102, 051805 (2009)], in which neutrino oscillation, dark matter, and baryon asymmetry of the Universe would be simultaneously explained by the TeV-scale physics without introducing very high mass scales. An exact discrete Z{sub 2} symmetry is introduced, under which new particle contents (a real singlet scalar field, a pair of charged singlet scalar fields, and TeV-scale right-handed neutrinos) are assigned to have odd quantum number, whereas ordinary gauge fields, quarks and leptons, and two Higgs doublets are even. Tiny neutrino masses aremore »« less

$Z^{}$ -portal right-handed neutrino dark matter in the minimal ${U (1)}_{X}$ extended Standard Model

Journal Article Okada, Nobuchika ; Okada, Satomi - Physical Review D

We consider a concise dark matter (DM) scenario in the context of a non-exotic U(1) extension of the Standard Model (SM), where a new U(1)_X gauge symmetry is introduced along with three generation of right-handed neutrinos (RHNs) and an SM gauge singlet Higgs field. The model is a generalization of the minimal gauged U(1)_B-L (baryon number minus lepton number) extension of the SM, in which the extra U(1)_X gauge symmetry is expressed as a linear combination of the SM U(1)_Y and U(1)_B-L gauge symmetries. We introduce a Z₂-parity and assign an odd-parity only for one RHN among all particles, somore »« less

Vacuum stability in inert higgs doublet model with right-handed neutrinos

Journal Article Jangid, Shilpa ; Bandyopadhyay, Priyotosh ; Dev, P. S. Bhupal ; ... - Journal of High Energy Physics (Online)

We analyze the vacuum stability in the inert Higgs doublet extension of the Standard Model (SM), augmented by right-handed neutrinos (RHNs) to explain neutrino masses at tree level by the seesaw mechanism. We make a comparative study of the high- and low-scale seesaw scenarios and the effect of the Dirac neutrino Yukawa couplings on the stability of the Higgs potential. Bounds on the scalar quartic couplings and Dirac Yukawa couplings are obtained from vacuum stability and perturbativity considerations. These bounds are found to be relevant only for low-scale seesaw scenarios with relatively large Yukawa couplings. The regions corresponding to stability,more »« less

Vector boson dark matter from trinification

Journal Article Babu, K. S. ; Jana, Sudip ; Thapa, Anil - Journal of High Energy Physics (Online)

We show how trinification models based on the gauge group SU(3)_C x SU(3)_L x SU(3)_R realized near the TeV scale can provide naturally a variety of dark matter (DM) candidates. These models contain a discrete T parity which may remain unbroken even after spontaneous symmetry breaking. The lightest T-odd particle, which could be a fermion, a scalar, or a gauge boson, can constitute the dark matter of the universe. This framework naturally admits a doublet-singlet fermionic DM, a singlet scalar DM, or a vector boson DM. Here we develop the vector boson DM scenario wherein the DM couples off-diagonally withmore »« less
