“…If this polarization does not change after the structure formation, the scenario predicts daily/annual modulation of the dark matter signals [81]. Since the regions that can be probed from the dark photon absorption by various materials [82][83][84][85][86][87][88][89][90][91][92] and in the experiments, Super-CDMS [84], LAMPOST [93], BREAD [94] (Dish-antenna experiment [95]), MADMAX [96], ALPHA [96], Dark E-field [97] and light shining through the wall experiments [98][99][100][101] is in the range of the post-inflation scenario (see figure 3), the discovery of the hidden photon in them, together with the dark radiation of ∆N eff = O(0.1) is another smoking-gun signal of the scenario.…”

“…The kinetic mixing scales as f −2 and can be probed by future experiments and observations depending on the value of f . Interestingly, the predicted kinetic mixing in the region of the post-inflationary scenario may be within reach of future experiments searching for dark photon absorption by various materials [82][83][84][85][86][87][88][89][90][91][92]. This can be also probed in LAMPOST [93], BREAD [94] (Dish-antenna experiment [95]), MADMAX [96], ALPHA [96], and Dark E-field [97].…”

We present a new mechanism to generate a coherently oscillating dark vector field from axion-SU(2) gauge field dynamics during inflation. The SU(2) gauge field acquires a nonzero background sourced by an axion during inflation, and it acquires a mass through spontaneous symmetry breaking after inflation. We find that the coherent oscillation of the dark vector field can account for dark matter in the mass range of 10-13 – 1 eV in a minimal setup. In a more involved scenario, the range can be wider down to the fuzzy dark matter region. One of the dark vector fields can be identified as the dark photon, in which case this mechanism evades the notorious constraints for isocurvature perturbation, statistical anisotropy, and the absence of ghosts that exist in the usual misalignment production scenarios. Phenomenological implications are discussed.

“…The lack of discovery of Weakly Interacting Massive Particles (WIMPs) at dark matter (DM) direct detection experiments has motivated the exploration of a variety of alternative theoretical and experimental paradigms over the past decade [1,2]. In this exploration, emphasis has been placed on probing DM candidates lying outside the canonical WIMP mass window, with most of these efforts focusing on the MeV-GeV mass range [3]. This choice is supported by at least three reasons [4].…”

Spin-1 thermal targets for dark matter searches at beam dump and fixed target experiments

The current framework for dark matter (DM) searches at beam dump and fixed target experiments primarily relies on four benchmark models, the so-called complex scalar, inelastic scalar, pseudo-Dirac and finally, Majorana DM models. While this approach has so far been successful in the interpretation of the available data, it a priori excludes the possibility that DM is made of spin-1 particles — a restriction which is neither theoretically nor experimentally justified. In this work we extend the current landscape of sub-GeV DM models to a set of models for spin-1 DM, including a family of simplified models (involving one DM candidate and one mediator — the dark photon) and an ultraviolet complete model based on a non-abelian gauge group where DM is a spin-1 Strongly Interacting Massive Particle (SIMP). For each of these models, we calculate the DM relic density, the expected number of signal events at beam dump experiments such as LSND and MiniBooNE, the rate of energy injection in the early universe thermal bath and in the Intergalactic Medium (IGM), as well as the helicity amplitudes for forward processes subject to the unitary bound. We then compare these predictions with experimental results from Planck, CMB surveys, IGM temperature observations, LSND, MiniBooNE, NA64, and BaBar and with available projections from LDMX and Belle II. Through this comparison, we identify the regions in the parameter space of the models considered in this work where DM is simultaneously thermally produced, compatible with present observations, and within reach at Belle II and, in particular, at LDMX. We find that the simplified models considered here are strongly constrained by current beam dump experiments and the unitarity bound, and will thus be conclusively probed (i.e. discovered or ruled out) in the first stages of LDMX data taking. We also find that the vector SIMP model explored in this work predicts the observed DM relic abundance, is compatible with current observations and within reach at LDMX in a wide region of the parameter space of the theory.

Dark matter substructures affect dark matter-electron scattering in xenon-based direct detection experiments

Recent sky surveys have discovered a large number of stellar substructures. It is highly likely that there are dark matter (DM) counterparts to these stellar substructures. We examine the implications of DM substructures for electron recoil (ER) direct detection (DD) rates in dual phase xenon experiments. We have utilized the results of the LAMOST survey and considered a few benchmark substructures in our analysis. Assuming that these substructures constitute 10% of the local DM density, we study the discovery limits of DM-electron scattering cross sections considering one kg-year exposure and 1, 2, and 3 electron thresholds. With this exposure and threshold, it is possible to observe the effect of the considered DM substructure for the currently allowed parameter space. We also explore the sensitivity of these experiments in resolving the DM substructure fraction. For all the considered cases, we observe that DM having mass $$ \mathcal{O}(10) $$ O 10 MeV has a better prospect in resolving substructure fraction as compared to $$ \mathcal{O}(100) $$ O 100 MeV scale DM. We also find that within the currently allowed DM-electron scattering cross-section; these experiments can resolve the substructure fraction (provided it has a non-negligible contribution to the local DM density) with good accuracy for $$ \mathcal{O}(10) $$ O 10 MeV DM mass with one electron threshold.
