Axion Dark Matter Search around 6.7 eV
arXiv:2001.05102 · doi:10.1103/PhysRevLett.124.101802
Abstract
An axion dark matter search with the CAPP-8TB haloscope is reported. Our results are sensitive to axion-photon coupling down to the QCD axion band over the axion mass range between 6.62 and 6.82 eV at a 90\% confidence level, which is the most sensitive result in the mass range to date.
