K ± → π ±a at next-to-leading order in chiral perturbation theory and updated bounds on ALP couplings

K ± → π ±a at next-to-leading order in chiral perturbation theory and updated bounds on ALP couplings

Abstract The weak decays K ± → π ± a offer a powerful probe of axion-like particles (ALPs). In this work, we provide a comprehensive analysis of these processes within chiral perturbation theory, extending existing calculations by including complete next-to-leading order (NLO) contributions and isos...
