We argue that previous treatments of such processes have used an incorrect representation of the flavor-changing quark currents in the chiral theory. As an application, we derive model-independent results for the decays $K^-\\to\\pi^- a$ and $\\pi^-\\to e^-\\bar\\nu_e a$ at leading order in the chiral expansion and for arbitrary axion couplings and mass. In particular, we find that the $K^-\\to\\pi^- a$ branching ratio is almost 40 times larger than previous","authors_text":"Andrea Thamm (U. Melbourne), Martin Bauer (U. Durham), Marvin Schnubel (U.
