Probing QCD Axions or axion-like particles in three-body K decays
Abstract Two-body decays like K → πa rank among the most constraining collider probes for new, low-mass, feebly interacting pseudoscalar particles a. We explore an alternative class of kaon decay modes, specifically three-body decays to ππa or μμa. The former occur at tree level, while the latter is...
