“…The kinetic mixing angle between the hidden and standard photon is naturally small -values χ h ∼ 10 −13 − 10 −2 are typically predicted in the literature [127][128][129][130][131][132][133][134][135][136][137][138]. The mixing leads to a number of observable consequences in laboratory experiments [139][140][141][142][143][144][145][146][147][148][149][150][151][152][153][154][155], astrophysics [156][157][158][159][160][161][162][163][164] and cosmology [165][166][167][168][169][170][171][172][173]…”

Axions and other very light axion-like particles appear in many extensions of the Standard Model, and are leading candidates to compose part or all of the missing matter of the Universe. They also appear in models of inflation, dark radiation, or even dark energy, and could solve some long-standing astrophysical anomalies. The physics case of these particles has been considerably developed in recent years, and there are now useful guidelines and powerful motivations to attempt experimental detection. Admittedly, the lack of a positive signal of new physics at the high energy frontier, and in underground detectors searching for weakly interacting massive particles, is also contributing to the increase of interest in axion searches. The experimental landscape is rapidly evolving, with many novel detection concepts and new experimental proposals. An updated account of those initiatives is lacking in the literature. In this review we attempt to provide such an update. We will focus on the new experimental approaches and their complementarity, but will also review the most relevant recent results from the consolidated strategies and the prospects of new generation experiments under consideration in the field. We will also briefly review the latest developments of the theory, cosmology and astrophysics of axions and we will discuss the prospects to probe a large fraction of relevant parameter space in the coming decade.

“…1 and 10 will also see improvements over the next few years. For example, upgraded LSW experiments [195][196][197], experiments using atomic transitions [125,198,199], or Aharanov-Bohm experiments [200,201] may improve the purely-laboratory bounds on DPs. Whereas searches using X-ray [202] and radio [203,204] telescopes, fast radio burst timing [205], or asteroseismology [206], may improve upon existing astrophysical bounds.…”

The dark photon is a massive hypothetical particle that interacts with the Standard Model by kinetically mixing with the visible photon. For small values of the mixing parameter, dark photons can evade cosmological bounds to be a viable dark matter candidate. Due to the similarities with the electromagnetic signals generated by axions, several bounds on dark photon signals are simply reinterpretations of historical bounds set by axion haloscopes. However, the dark photon has a property that the axion does not: an intrinsic polarisation. Due to the rotation of the Earth, accurately accounting for this polarisation is nontrivial, and highly experiment-dependent. We show that if one does account for this polarisation, and the rotation of the Earth, experimental sensitivity to the dark photon's kinetic mixing parameter can be improved by over an order of magnitude. We detail the strategies that would need to be taken to properly optimise a dark photon search. These include judiciously choosing the location and orientation of the experiment, as well as strategically timing any repeated measurements. We also point out that several well-known searches for axions employ techniques for testing signals that preclude their ability to set exclusion limits on dark photons, and hence should not be reinterpreted as such.
