In the context of a left-right symmetric model, we introduce one full generation of vectorlike lepton doublets (both left and right-handed) together with their mirror doublets. We show that the lightest vectorlike neutrino in the model is right-handed, and can serve as the dark matter candidate. We find that the relic density as well as the direct and indirect DM detection bounds are satisfied for a large range of the parameter space of the model. In accordance with the parameter space, we then explore the possibility of detecting signals of the model at both the LHC and the ILC, in the pair production of the associated vectorlike charged leptons which decay into final states including dark matter. A comprehensive analysis of signal and backgrounds shows that the signals at the ILC, especially with polarized beams are likely to be visible for light vectorlike leptons, even with low luminosity, rendering our model highly predictable and experimentally testable.

“…Since then, this is one of the existing strategies to indirectly detect DM, which is in turn complementary to DM direct searches, given that in both cases the signal would be proportional to the DM elastic scattering cross section. Indeed, numerous studies have evaluated the prospects of detection of the potential high-energy neutrino flux and of that of neutrinos in the O(10-100) MeV range [72][73][74][75] using neutrino detectors/telescopes [76][77][78][79][80][81][82][83][84][85][86][87][88][89]. All these works have focused on DM-nucleon interactions.…”

The annihilation of dark matter (DM) particles accumulated in the Sun could produce a flux of neutrinos, which is potentially detectable with neutrino detectors/telescopes and the DM elastic scattering cross section can be constrained. Although the process of DM capture in astrophysical objects like the Sun is commonly assumed to be due to interactions only with nucleons, there are scenarios in which tree-level DM couplings to quarks are absent, and even if loop-induced interactions with nucleons are allowed, scatterings off electrons could be the dominant capture mechanism. We consider this possibility and study in detail all the ingredients necessary to compute the neutrino production rates from DM annihilations in the Sun (capture, annihilation and evaporation rates) for velocity-independent and isotropic, velocity-dependent and isotropic and momentum-dependent scattering cross sections for DM interactions with electrons and compare them with the results obtained for the case of interactions with nucleons. Moreover, we improve the usual calculations in a number of ways and provide analytical expressions in three appendices. Interestingly, we find that the evaporation mass in the case of interactions with electrons could be below the GeV range, depending on the high-velocity tail of the DM distribution in the Sun, which would open a new mass window for searching for this type of scenarios.

“…These were derived for other Z models than the one considered here, so we have reanalyzed the ATLAS data to constrain the purely kinetically mixed Z , as described in appendix E. In figure 5(a) we show the limits on σBR for Z → e + e − and Z → µ + µ − , where BR denotes the branching ratio for Z to decay into these final states. Assuming that there are no invisible decays, the predicted values of σBR for models with 2 Stronger limits on SD scattering on protons in the sun have been obtained by neutrino detection experiments [21,22]. These depend upon the efficiency of getting neutrinos from the decays of final state particles from χχ annihilation.…”

One of the simplest hidden sectors with signatures in the visible sector is fermionic dark matter χ coupled to a Z gauge boson that has purely kinetic mixing with the standard model hypercharge. We consider the combined constraints from relic density, direct detection and collider experiments on such models in which the dark matter is either a Dirac or a Majorana fermion. We point out sensitivity to details of the UV completion for the Majorana model. For kinetic mixing parameter ≤ 0.01, only relic density and direct detection are relevant, while for larger , electroweak precision, LHC dilepton, and missing energy constraints become important. We identify regions of the parameter space of m χ , m Z , dark gauge coupling and that are most promising for discovery through these experimental probes. We study the compatibility of the models with the galactic center gamma ray excess, finding agreement at the 2-3σ level for the Dirac model.
