“…Over the years, several attempts have been made to connect neutrino physics with dark matter [196][197][198][199][200][201][202][203][204][205][206][207]. In a toy example [204], the authors showed a one-to-one correspondence with WIMP dark matter and type-I seesaw.…”

We discuss neutrino mass and mixing models based on discrete flavor symmetries. These models can include a variety of new interactions and non-standard particles such as sterile neutrinos, scalar Higgs singlets and multiplets. We point at connections of the models with leptogenesis and dark matter and the ways to detect the corresponding non-standard particles at intensity and energy frontier experiments.

“…The presence of right handed neutrinos in the seesaw realization of light neutrino mass provides an opportunity to study leptogenesis from the CP-violating out-of-equilibrium decay of RH neutrinos into lepton and Higgs doublets in the early universe [21,25,70]. The lepton asymmetry created is expected to be converted to a baryon asymmetry via the sphaleron process.…”

We propose a minimal A 4 flavor symmetric model, assisted by Z 2 × Z 3 symmetry, which can naturally takes care of the appropriate lepton mixing and neutrino masses via Type-I seesaw.It turns out that the framework, originated due to a specific flavor structure, favors the normal hierarchy of light neutrinos and simultaneously narrows down the range of Dirac CP violating phase.It predicts an interesting correlation between the atmospheric mixing angle and the Dirac CP phase too. While the flavor structure indicates an exact degeneracy of the right handed neutrino masses, renormalization group running of the same from a high scale is shown to make it quasi-degenerate and a successful flavor leptogenesis takes place within the allowed parameter space obtained from neutrino phenomenology.

“…Amongst recent theoretical efforts, of particular interest are those suggesting minimal extensions to the Standard Model (SM) to address the seemingly unrelated sectors of neutrinos, DM and excess of baryonic matter over anti-baryonic one in a unified framework [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]. However, the requirement of tiny neutrino mass, a very specific DM relic density together with the fine-tuned matter-anti matter asymmetry leads naturally to heavy BSM physics or those weakly coupled to visible sector.…”

We analyse a model that connects the neutrino sector and the dark sector of the universe via a mediator Φ, stabilised by a discrete 𝒵 4 symmetry that breaks to a remnant 𝒵 2 upon Φ acquiring a non-zero vacuum expectation value (vϕ ). The model accounts for the observed baryon asymmetry of the universe via additional contributions to the canonical Type-I leptogenesis. The 𝒵 4 symmetry breaking scale (vϕ ) in the model not only establishes a connection between the neutrino sector and the dark sector, but could also lead to gravitational wave signals that are within the reach of current and future experimental sensitivities.
