15. Axion research at IBS/CAPP

The axion is a hypothetical particle of the Peccei-Quinn solution to the strong-CP problem in particle physics. With some constraints on mass, it also possesses a cosmological implication to account for cold dark matter. Since 2013, IBS/CAPP has been establishing state of the art experiments to search for axion dark matter in Korea. Relying on the cavity haloscope, multiple experiments are...

16. Axion scales and couplings with Stückelberg mixing

In this talk, I will discuss about the axion field range and low energy couplings in models with Stückelberg mixing between axions and U(1) gauge bosons. It is noted that the gauge-invariant axion combination in the model is periodic modulo an appropriate shift of gauge-variant axions eaten by the massive U(1) gauge bosons, which in some cases makes the connection between the field range and...
