“…It is important to first notice that the Z gauge boson arising from the L µ − L τ local symmetry dictates a dark matter phenomenology rather different from other realizations of a "dark Z portal" (see e.g. [67][68][69][70][71][72][73][74][75][76][77][78][79][80][81][82][83][84]). For example, the dark matter pair annihilation exclusively yields muon, tau, and neutrino pairs, as well as Z boson pairs, if kinematically allowed (i.e.…”

We present a dark sector model based on gauging the L µ − L τ symmetry that addresses anomalies in b → sµ + µ − decays and that features a particle dark matter candidate. The dark matter particle candidate is a vector-like Dirac fermion coupled to the Z gauge boson of the L µ − L τ symmetry. We compute the dark matter thermal relic density, its pair-annihilation cross section, and the loop-suppressed dark matter-nucleon scattering cross section, and compare our predictions with current and future experimental results. We demonstrate that after taking into account bounds from B s meson oscillations, dark matter direct detection, and the CMB, the model is highly predictive: B physics anomalies and a viable particle dark matter candidate, with a mass of ∼ (5 − 23) GeV, can be accommodated only in a tightly-constrained region of parameter space, with sharp predictions for future experimental tests. The viable region of parameter space expands if the dark matter is allowed to have L µ − L τ charges that are smaller than those of the SM leptons.

“…Aside from an overall rescaling, we assume that the Z has similar couplings to SM Z, an assumption studied in the previous literature [7,11,12]. By studying regimes in which the Z -SM fermion couplings are suppressed by an overall factor, we implicitly encompass several SM extensions such as sequential Z models [13], 3-3-1 models [14,15], E-6 models [16], Left-Right [17], etc. We present results for a broad range of particle DM masses, specifically: 8 GeV, 15 GeV, 50 GeV, 500 GeV, 1 TeV, and 5 TeV, with Z − χ − χ couplings ranging from 10 −5 − 10.…”

Z gauge bosons arise in many particle physics models as mediators between the dark and visible sectors. We exploit dark matter complementarity and derive stringent and robust collider, direct and indirect constraints, as well as limits from the muon magnetic moment. We rule out almost the entire region of the parameter space that yields the right dark matter thermal relic abundance, using a generic parametrization of the Z -fermion couplings normalized to the Standard Model Z-fermion couplings for dark matter masses in the 8 GeV-5 TeV range. We conclude that mediators lighter than 2.1 TeV are excluded regardless of the DM mass, and that depending on the Z − f ermion coupling strength much heavier masses are needed to reproduce the DM thermal relic abundance while avoiding existing limits.

A Brief Review on WIMPs in 331 Electroweak Gauge Models

Abstract:In this study we review the cold dark matter problem in the context of a class of models which are a simple extension of the electroweak standard model, where the gauge symmetry is dictated by the group structure, SU(3) c ⊗SU(3)L⊗U(1) X . This model, in different versions, has been able to address many interesting facts not explained by the standard model. It would be just desirable that the dark matter issue could be contemplated as well, since the problem of the missing matter has become one of the greatest indications of incompleteness of currently established theories describing the known interactions and the cosmological evolution and content of the observed Universe. We do that by pointing out some of the successful steps in this direction and remarking some sources of difficulties concerning their phenomenological and theoretical implementation.
