【 摘 要 】

I review the set of theoretical ideas motivating experimental searches of light physics beyond the Standard Model. Specifically, I give examples of very weakly interacting candidates that can be probed in direct detection experiments. I then discuss a possibility of probing such states in the high-intensity kaon experiments by looking at the rare and radiate decay modes. The interesting modes to pursue include K±→ π±+ missing energy, K±→ π±π0e+e-, as well as Dalitz and double-Dalitz decays of π0.
