Kaon Flavour Physics Strikes Back

In this short presentation I emphasize the increased importance of kaon avour physics in the search for new physics (NP) that we should witness in the rest of this decade and in the next decade. The main actors will be the branching ratios for the rare decays K⁺ → φ⁺v v and K_L →⁰ v v, to be measured by NA62 and KOTO, and their correlations with the ratio ϵ/ϵ on which recently progress by lattice QCD and large N dual QCD approach has been made implying a new avour anomaly. Further correlations of K⁺ φ⁺ v v, K_Lπ⁰ v v and ϵ= ϵ with ϵ_K, ΔM_K, K_L →μ⁺μ^- and K_Lφ⁰ℓ⁺ℓ^- will help us to identify indirectly possible NP at short distance scales. This talk summarizes the present highlights of this facinating field including some results from concrete NP scenarios.
