Abstract: Flavor probes, in particular rare kaon decays, provide some of the strongest constraints on ALP couplings.
Rare neutral kaon decays also provide a unique probe to the CP properties of ALP couplings. In this talk I will present a first calculation of the 3-body neutral kaon decay rates, first by showing how the required flavor- and CP-violating couplings are generated from the UV theory. I will discuss the symmetry properties of the amplitudes and compare the rates from 2- and 3-body neutral kaon decays for a few benchmark cases. Finally, I will present some of the phenomenological implications.
