“…We note that while the analysis of ref. [95] does not include Pauli blocking effects, the above bound converts into an effective suppression scale of the dimension-five dipole operator of order ∼ 10 9 GeV, which is comparable to the constraint on the suppression scale of the axion-photon coupling from supernova cooling considerations [69]. We thus believe the order of magnitude of the constraint is valid.…”

We examine in greater detail the recent proposal of using superconductors for detecting dark matter as light as the warm dark matter limit of O(keV). Detection of such light dark matter is possible if the entire kinetic energy of the dark matter is extracted in the scattering, and if the experiment is sensitive to O(meV) energy depositions. This is the case for Fermi-degenerate materials in which the Fermi velocity exceeds the dark matter velocity dispersion in the Milky Way of ∼ 10 −3 . We focus on a concrete experimental proposal using a superconducting target with a transition edge sensor in order to detect the small energy deposits from the dark matter scatterings. Considering a wide variety of constraints, from dark matter self-interactions to the cosmic microwave background, we show that models consistent with cosmological/astrophysical and terrestrial constraints are observable with such detectors. A wider range of viable models with dark matter mass below an MeV is available if dark matter or mediator properties (such as couplings or masses) differ at BBN epoch or in stellar interiors from those in superconductors. We also show that metal targets pay a strong in-medium suppression for kinetically mixed mediators; this suppression is alleviated with insulating targets.

New particles χ that are electrically neutral but couple to the electromagnetic current via higherdimensional operators and that are sufficiently light, at or below the GeV-mass scale, can be produced in pairs in a number of dedicated high-intensity experiments. In this work we consider the production of χ through magnetic-and electric-dipole moments as well as through anapole moment and charge radius interactions in electron beams. We derive new constraints from BaBar, NA64 and mQ and forecast the future sensitivity on the existence of such states, from Belle-II, LDMX and BDX. We present for the first time a detailed treatment of the off-shell production of photons in electron beams with subsequent decay into a χχ pair in a 2-to-4 process. These direct limits are then compared to the effects on SM precision observables, as well as to bounds from flavor physics and high energy colliders. Finally, we consider the possibility that χ is dark matter and study ensuing astrophysical and cosmological constraints. We find that a combination of all considered probes rule out χ particles with mass-dimension five and six photon interactions as dark matter when assuming a standard freeze-out abundance.

“…Our specific example, the velocity-dependent elastic scattering cross-section, would be also of great interest for particle physics studies because of its infrared enhancement for a low momentum transfer, which has been explored for potential signals beyond the standard model at collider and dark matter search experiments [21,23,24,25,26]. Such probes of the dark matter properties from both cosmology and particle physics deserve further study in view of forthcoming experiments which can explore the nature of the DM coupling to ordinary baryons.…”

“…The spectral index n depends on the nature of DM models, for instance, n = −1 corresponds to the Yukawa-type potential DM , n = −2, −4 are respectively for dipole DM and millicharged DM [3,4,5,6,20,21,22,23,24,25,26]. The constant coefficient c n depends on the value of n and also can include the correction factor for including the helium in addition to hydrogen.…”

We demonstrate that elastic scattering between dark matter (DM) and baryons can affect the thermal evolution of the intergalactic medium at early epochs and discuss the observational consequences. We show that, due to the interaction between DM and baryons, the baryon temperature is cooled after decoupling from the CMB temperature. We illustrate our findings by calculating the 21 cm power spectrum in coexistence with a velocity-dependent DM elastic scattering cross section. For instance, for a DM mass of 10 GeV, the 21 cm brightnesstemperature angular power spectrum can be suppressed by a factor 2 within the currently allowed DM-baryon cross section bounded by the CMB and large-scale structure data. This scale-independent suppression of the angular power spectrum can be even larger for a smaller DM mass with a common cross section (for instance, as large as a factor 10 for m d ∼ 1 GeV), and such an effect would be of great interest for probing the nature of DM in view of forthcoming cosmological surveys.
