Weak nuclear decays deep-underground as a probe of axion dark matter

We investigate the time modulation of weak nuclear decays as a method to probe axion dark matter. To this end, we develop a theoretical framework to compute the θ dependence of weak nuclear decays, including electron capture and β decay, which enables us to predict the time variation of weak radioac...
