“…where E and v a are the ALP's energy and velocity, respectively [2,17,18]. We infer that the rate of absorption of non-relativistic ALP DM on an electron (n a σ AE v a , where n a is the ALP number density) has negligible dependence on v a .…”

“…We show existing bounds and projections in the g aee versus m a parameter space. The ALP interaction with electrons is responsible for the "axioelectric" effect [2,17,18,54]. In analogy to the photoelectric effect, axions may be absorbed by bound electrons, ionizing them.…”

“…This interaction allows the axion or ALP to be absorbed in a target material, rather than scattering off it. The case of absorption in bound electrons, known as the axioelectric effect, has been originally suggested in [17,18]. Numerous direct-detection experiments have conducted searches assuming that the ALP constitutes the galactic DM or is produced in the Sun, including CoGeNT [19], CDMS [20], EDEL-WEISS [21], XENON100 [22], and KIMS [23].…”

We consider the absorption by bound electrons of dark matter in the form of dark photons and axion-like particles, as well as of dark photons from the Sun, in current and next-generation direct detection experiments. Experiments sensitive to electron recoils can detect such particles with masses between a few eV to more than 10 keV. For dark photon dark matter, we update a previous bound based on XENON10 data and derive new bounds based on data from XENON100 and CDMSlite. We find these experiments to disfavor previously allowed parameter space. Moreover, we derive sensitivity projections for SuperCDMS at SNOLAB for silicon and germanium targets, as well as for various possible experiments with scintillating targets (cesium iodide, sodium iodide, and gallium arsenide). The projected sensitivity can probe large new regions of parameter space. For axionlike particles, the same current direction detection data improves on previously known direct-detection constraints but does not bound new parameter space beyond known stellar cooling bounds. However, projected sensitivities of the upcoming SuperCDMS SNOLAB using germanium can go beyond these and even probe parameter space consistent with possible hints from the white dwarf luminosity function. We find similar results for dark photons from the sun. For all cases, direct-detection experiments can have unprecedented sensitivity to dark-sector particles.

“…Axions and ALPs may give rise to observable signatures in detectors through their coupling to photons (g Aγ ), electrons (g Ae ) and nuclei (g AN ). The coupling g Ae may be tested via scattering off the electron of a target, such as liquid xenon (LXe), through the axio-electric effect [11][12][13][14][15]. This process is the analogue of the photoelectric process with the absorption of an axion instead of a photon.…”

We present the first results of searches for axions and axion-like-particles with the XENON100 experiment. The axion-electron coupling constant, gAe, has been probed by exploiting the axioelectric effect in liquid xenon. A profile likelihood analysis of 224.6 live days × 34 kg exposure has shown no evidence for a signal. By rejecting gAe larger than 7.7 × 10 −12 (90% CL) in the solar axion search, we set the best limit to date on this coupling. In the frame of the DFSZ and KSVZ models, we exclude QCD axions heavier than 0.3 eV/c 2 and 80 eV/c 2 , respectively. For axion-like-particles, under the assumption that they constitute the whole abundance of dark matter in our galaxy, we constrain gAe to be lower than 1 × 10 −12 (90% CL) for mass range from 1 to 40 keV/c 2 , and set the best limit to date as well.

Abstract. The XENON100 experiment is the second phase of the XENON direct Dark Matter search program. It consists of an ultra-low background double phase (liquid-gas) xenon filled time projection chamber with a total mass of 161 kg (62 in the target region and 99 in the active shield), installed at the Laboratori Nazionali del Gran Sasso (LNGS). Here the results from the 224.6 live days of data taken between March 2011 and April 2012 are reported. The experiment set one of the most stringent limits on the WIMPnucleon spin-independent cross section to date (2 × 10 −45 cm 2 for a 55 Gev/c 2 WIMP mass at 90 % confidence level) and the most stringent on the spin-dependent WIMPneutron interaction (3.5 × 10 −40 for a 45 GeV/c 2 WIMP mass). With the same dataset, XENON100 excludes also solar axion coupling to electrons at g Ae > 7.7 × 10 −12 for a mass of m Axion <1 keV/c 2 and galactic axion couplings by g Ae > 1 × 10 −12 at a mass range of m Axion = 5 − 10 keV/c 2 (both 90 % C.L.). Moreover an absolute spectral comparison between simulated and measured nuclear recoil distributions of light and charge signals from a 241 AmBe source demonstrates a high level of detector and systematics understanding. Finally, the third generation of the XENON experiments, XENON1T, is the first tonne scale direct WIMP search experiment currently under construction. The commissioning phase of XENON1T is expected to start in early 2015 followed, a few months after, by the first science run. The experiment will reach sensitivities on the WIMP-nucleon spin-independent cross section down to 2 ×10 −47 cm 2 after two years of data taking.
