“…The dark photon-photon kinetic mixing 1 2 εF µνF µν (see e.g., Refs. [18,[46][47][48][49][50][51][52] for more) bridges new transitions between millicharged DM and the standard model (SM) particles, with the field strengthsF andF corresponding to electromagnetism fieldÂ and dark electromagnetism fieldÂ respectively. The mass of dark photon can be obtained via Higgs-like mechanism or Stueckelberg mechanism [53].…”

The CMB observation sets stringent constraints on MeV dark matter (DM) annihilating into charged states/photons in s-wave, and the recent observation of the 21-cm absorption at the cosmic dawn reported by EDGES is also very strict for s-wave annihilations of MeV DM. The millicharged DM with p-wave dominant annihilations during the freeze-out period are considered in literatures to give an explanation about the 21-cm absorption, with photon mediated scattering cooling the hydrogen. In this paper, we focus on the annihilation of millicharged DM being s-wave dominant. To explain the 21-cm absorption and meanwhile be compatible with the CMB and 21-cm absorption bounds on DM annihilations, we consider the annihilation close to the resonance, with the new mediator (here is dark photon) mass being slightly above twice of the millicharged DM mass. In this case, the annihilation cross section at the temperature T → 0 could be much smaller than that at T f , which would be tolerated by the bounds on DM annihilations, avoiding the excess heating from DM s-wave annihilations to the hydrogen gas. The beam dump and lepton collider experiments can be employed to hunt for millicharged DM via the production of the invisible dark photon.

“…Attempts to explain the existence of dark matter by extending the symmetry group U(1) have been made long ago (see, for example, [11][12][13] and the references therein). Numerous publications have appeared on this subject over the past ten years, and now such concepts as dark sector containing a Higgs field, 'dark photons' coupled to visible photons, are frequently considered extensions of the Standard Model because of their possible connection to dark matter ([4, [14][15][16][17][18]). The nature of dark matter is maintained through the hidden sector which contains an additional copy of U(1) associated with new particles.…”

The idea of a new model explaining the coherent nature of dark matter and dark energy is proposed. Recent works by Farnes (2018) and Socas-Navarro (2019) proposed a cosmological model and its critical analysis in which both dark matter and dark energy are replaced with a single fluid of negative mass. This paper presents a modification of this idea using the hypothesis about the existence of so-called imaginary charges and electromagnetic fields with negative energy density (‘minus-fields’) proposed by Ya.Terletsky (1991) and derived by us from a commutative generalization of the U(1) gauge symmetry group. It is shown that dark photons could be a partial source of the observed late-time cosmological acceleration, saying that dark energy, or part of it could be not cosmological constant or scalar field (quintessence), but photons with negative energy instead. The unusual properties of imaginary charges ensure the existence of dark matter structures. The Friedmann equation, in case when minus-photons give considerable contribution to the energy balance of the Universe, gives the following condition for the accelerated expansion: . It is found that even a relatively small density of dark negative radiation can lead to a significant change in the expansion dynamics of the Universe and new effects are predicted. Last, we assert the need to develop a new type of detectors that can detect particles and waves with negative energy.

“…Later, the axion-Proca ED was obtained as an effective field theory in a Condensed Matter system [54]. Recently, new extensions involving a hidden photon (another massive dark matter candidate) coupled to the axion and photon fields have been proposal in the literature [55,56]. The propagation effects in the presence of extra CPT-odd terms also motivate other extensions of the Maxwell ED [57].…”

In this contribution, we re-assess some aspects of axionic electrodynamics by coupling non-linear electromagnetic effects to axion physics. We present a number of motivations to justify the coupling of the axion to the photon in terms of a general non-linear extension of the electromagnetic sector. Our emphasis in the paper relies on the investigation of the constitutive permittivity and permeability tensors, for which the axion contributes by introducing dependence on the frequency and wave vector of the propagating radiation. Also, we point out how the axion mass and the axion-photon-photon coupling constant contribute to a dispersive behavior of the electromagnetic waves, in contrast to what happens in the case of non-linear extensions, when effective refractive indices appear which depend only on the direction of the propagation with respect to the external fields. The axion changes this picture by yielding refractive indices with dependence on the wavelength. We apply our results to the special case of the (non-birefringent) Born-Infeld Electrodynamics and we show that it becomes birefringent whenever the axion is coupled. The paper is supplemented by an appendix, where we follow our own path to approach the recent discussion on a controversy in the definition of the Poynting vector of axionic electrodynamics.
