“…The Z channel also provides a tree-level spin-independent direct detection signature. It is well known that these two constraints (freeze-out relic density and direct detection bounds) are in tension for m χ < O(10 TeV) in U( 1) models [58][59][60][61][62][63][64][65]. For DM masses below O(10) GeV the direct detection bounds are much less stringent, due to poor detector sensitivity to nuclear recoils induced by the light dark matter.…”

We explore the possibility of having a fermionic dark matter candidate within U(1)′ models for CEνNS experiments in light of the latest COHERENT data and the current and future dark matter direct detection experiments. A vector-like fermionic dark matter has been introduced which is charged under U(1)′ symmetry, naturally stable after spontaneous symmetry breaking. We perform a complementary investigation using CEνNS experiments and dark matter direct detection searches to explore dark matter as well as Z′ boson parameter space. Depending on numerous other constraints arising from the beam dump, LHCb, BABAR, and the forthcoming reactor experiment proposed by the SBC collaboration, we explore the allowed region of Z′ portal dark matter.

“…Using the freeze-out temperatures T D F O and T ν R F O we add the contributions in Eqs. (34) and (35) to confront against the limit set by 5 PLANCK+BAO [2] N eff = 2.96 +0.34 −0.33 (36) In the right panel of Fig. 2 one sees the resulting restrictions as a function of m BL /g BL for various sin θ h values.…”

“…This implies that there are two generic portals connecting our scotogenic WIMP dark matter to the SM particles. Each of these individual portals has been worked out extensively in the literature [12,[32][33][34][35][36][37]. In order to comply with the LEP bounds on charged scalars, we restrict ourselves to dark scalar mediator masses m ϕ2,η + 100 GeV [38].…”

“…Spin-independent scattering with nuclei occurs via Z BL exchange, and is expected to be important because the Z BL couples to quarks without suppression. Previous analyses have found that large regions in the (m S1 , m BL ) plane are excluded by over-abundance or direct detection bounds[32][33][34], except for the tip of a cusp-like region along the 2m S1 ≈ m BL resonant line.As mentioned in Sec. III B, Z BL exchange between RHN and SM fermions contributes to ∆N eff , see solid curve in the right panel of Fig.2.…”

We analyze a model with unbroken U (1)B−L gauge symmetry where neutrino masses are generated at one loop, after spontaneous breaking of a global U (1)G symmetry. These symmetries ensure dark matter (DM) stability and the Diracness of neutrinos. Within this context, we examine fermionic dark matter. Consistency between the required neutrino mass and the observed relic abundance indicates dark matter masses and couplings within the reach of direct detection experiments.

The extension of the Standard model (SM) with three heavy right handed neutrinos, a complex scalar and the gauged U(1)B−L symmetry (the minimal B − L model) is considered the most compelling minimal one: the presence and the out-of-equilibrium decay of the heavy right handed neutrinos can account for the small masses of the active neutrinos and the baryon asymmetry of the universe. A natural accompanying question concerns whether the minimal B − L model can naturally accommodate an interesting dark matter (DM) candidate. We study the possibility where the current DM population is explained by the gauge boson of U(1)B−L symmetry. We discuss how the minimal set-up originally aimed at the seesaw mechanism and the leptogenesis is connected to conditions making the gauge boson promoted to a DM candidate.
