“…The expected sensitivity, based on the background hypothesis, is shown by the green/yellow bands (1σ/2σ). Limits by EDELWEISS-II [31], and XMASS [32] are shown, together with the limits from a Si(Li) detector from Derbin et al [33]. Indirect astrophysical bounds from solar neutrinos [34] and red giants [35] are represented by dashed lines.…”

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 results of a search for solar axions from the Korea Invisible Mass Search (KIMS) experiment at the Yangyang Underground Laboratory are presented. Low-energy electron-recoil events would be produced by conversion of solar axions into electrons via the axio-electric effect in CsI(Tl) crystals. Using data from an exposure of 34,596 kg · days, we set a 90 % confidence level upper limit on the axion-electron coupling, g ae , of 1.39 × 10 −11 for an axion mass less than 1 keV/c 2 . This limit is lower than the indirect solar neutrino bound, and fully excludes QCD axions heavier than 0.48 eV/c 2 and 140.9 eV/c 2 for the DFSZ and KSVZ models respectively.

“…The axion-electron coupling is a model-dependent coupling. In the DFSZ model, g ae is proportional to cos 2 β [19], where cot β is the ratio of the two Higgs vacuum expectation values of the model [37]. In the KSVZ model, it depends on E/N [19], where E and N are the electromagnetic and color anomaly of the axial current associated with the axion field [37].…”

We present results from a search for solar axions with the COSINE-100 experiment. We find no evidence of solar axion events from a data-set of 6,303.9 kg·days exposure and set a 90 % confidence level upper limit on the axionelectron coupling, g ae , of 1.70 × 10 −11 for an axion mass less than 1 keV/c 2 . This limit excludes QCD axions heavier than 0.59 eV/c 2 in the DFSZ model and 168.1 eV/c 2 in the KSVZ model.
