Constraints on Axion couplings from the CDEX-1 experiment at the China Jinping Underground Laboratory

Abstract

We report the results of searches for solar axions and galactic dark matter axions or axion-like particles with CDEX-1 experiment at the China Jinping Underground Laboratory, using 335.6 kg-days of data from a p-type point-contact germanium detector. The data are compatible with the background model and no excess signals are observed. Limits of solar axions on the model independent coupling $g_{Ae}<2.5\times 10^{-11}$ from Compton, bremsstrahlung, atomic-recombination and deexcitation channel and $g_{AN}^{\text{eff}}\times g_{Ae}<6.1\times 10^{-17}$ from ${}^{57}$Fe M1 transition at 90 % confidence level are derived. Within the framework of the DFSZ and KSVZ models, our results exclude the axion mass heavier than 0.9 eV/c${}^2$ and 173 eV/c${}^2$, respectively. The derived constraints for dark matter axions below 1 keV improves over the previous results.
