AI Article Synopsis
- - The Taiwan Axion Search Experiment with a Haloscope focused on detecting axions by utilizing a microwave cavity in the frequency range of 4.70750 to 4.79815 GHz.
- - The experiment did not find any significant axion signals, with the highest significance being 3.355, but it was able to exclude certain theoretical models of axion interactions.
- - This study achieved unprecedented sensitivity, improving constraints on axion-two-photon coupling in the mass range of 19.4687 to 19.7639 μeV, surpassing previous nonhaloscope experiments by three orders of magnitude.
Article Abstract
This Letter reports on the first results from the Taiwan Axion Search Experiment with a Haloscope, a search for axions using a microwave cavity at frequencies between 4.707 50 and 4.798 15 GHz. Apart from the nonaxion signals, no candidates with a significance of more than 3.355 were found. The experiment excludes models with the axion-two-photon coupling |g_{aγγ}|≳8.1×10^{-14} GeV^{-1}, a factor of eleven above the benchmark Kim-Shifman-Vainshtein-Zakharov model, in the mass range 19.4687
