“…In the last two decades the Axion Dark Matter Experiment -ADMX -has implemented this method for cavities in the GHz range. Under the assumption of dominant DM component for the axion, ADMX has excluded the KSVZ axion in the 1.91 -3.69 µeV mass range [164], and very recently the DFSZ one in the 2.66 -2.81 µeV range [158]. The apparatus is based on a large volume high Q tunable copper cavity, operated in the sub K temperature range and read by a SQUID based detection chain.…”

The Physics Beyond Colliders initiative is an exploratory study aimed at exploiting the full scientific potential of the CERN's accelerator complex and scientific infrastructures through projects complementary to the LHC and other possible future colliders.

These projects would target fundamental physics questions that are similar in spirit to those addressed by high-energy colliders, but that require different types of beams and experiments 1 ". Fundamental questions in modern particle physics as the origin of the neutrino masses and oscillations, the nature of Dark Matter and the explanation of the mechanism that drives the baryogenesis are still open today and do require an answer.So far an unambiguous signal of New Physics (NP) from direct searches at the Large Hadron Collider (LHC), indirect searches in flavour physics and direct detection Dark Matter experiments is absent. Moreover, theory provides no clear guidance on the NP scale. This imposes today, more than ever, a broadening of the experimental effort in the quest for NP. We need to explore different ranges of interaction strengths and masses with respect to what is already covered by existing or planned initiatives.Low-mass and very-weakly coupled particles represent an attractive possibility, theoretically and phenomenologically well motivated, but currently poorly explored: a systematic investigation should be pursued in the next decades both at acc...

“…Dark matter (DM) is generally thought to be a stable particle (or particles) not part of the standard model; however, it has so far remained elusive [1][2][3][4][5][6][7]. Cosmologically, it is usually modeled as cold dark matter (CDM), which is part of the successful ΛCDM model that is consistent with observations of the cosmic microwave background (CMB) (e.g., [8]), cosmic shear surveys (e.g., [9]), measurements of the background expansion such as BAO probes [10], supernovae distance measurements [11], and the observed abundance of light elements [12].…”

Dark Matter Equation of State through Cosmic History

Cold dark matter is a crucial constituent of the current concordance cosmological model. Having a vanishing equation of state (EOS), its energy density scales with the inverse cosmic volume and is thus uniquely described by a single number, its present abundance. We test the inverse cosmic volume law for dark matter (DM) by allowing its EOS to vary independently in eight redshift bins in the range z ¼ 10 5 and z ¼ 0. We use the latest measurements of the cosmic microwave background radiation from the Planck satellite and supplement them with baryon acoustic oscillation (BAO) data from the 6dF and SDSS-III BOSS surveys and with the Hubble Space Telescope (HST) key project data. We find no evidence for nonzero EOS in any of the eight redshift bins. With Planck data alone, the DM abundance is most strongly constrained around matter-radiation equality ω (95% C.L.), respectively. Our results constrain for the first time the level of "coldness" required of the DM across various cosmological epochs and show that the DM abundance is strictly positive at all times.

“…The Axion Dark Matter eXperiment (ADMX) is the most sensitive haloscope detector based on high quality factor microwave resonators at cryogenic temperature. ADMX searches have excluded the mass range 1.9 < m a < 3.69 μ eV 18,19 . The experiment HAYSTAC (formally ADMX-High Frequency) 20 , designed specifically to search for axions in the 20–100 μ eV range (5–25 GHz), has recently reached cosmologically relevant sensitivity at 24 μ eV (~5.8 GHz).…”

Axion dark matter detection by laser induced fluorescence in rare-earth doped materials

We present a detection scheme to search for QCD axion dark matter, that is based on a direct interaction between axions and electrons explicitly predicted by DFSZ axion models. The local axion dark matter field shall drive transitions between Zeeman-split atomic levels separated by the axion rest mass energy m a c 2. Axion-related excitations are then detected with an upconversion scheme involving a pump laser that converts the absorbed axion energy (~hundreds of μeV) to visible or infrared photons, where single photon detection is an established technique. The proposed scheme involves rare-earth ions doped into solid-state crystalline materials, and the optical transitions take place between energy levels of 4f N electron configuration. Beyond discussing theoretical aspects and requirements to achieve a cosmologically relevant sensitivity, especially in terms of spectroscopic material properties, we experimentally investigate backgrounds due to the pump laser at temperatures in the range 1.9 − 4.2 K. Our results rule out excitation of the upper Zeeman component of the ground state by laser-related heating effects, and are of some help in optimizing activated material parameters to suppress the multiphonon-assisted Stokes fluorescence.
