  "abstract": "Recent calculations have pointed to a 2.8 $\\sigma$ tension between data on $\\epsilon^{\\prime}_K / \\epsilon_K$ and the standard-model (SM) prediction. Several new physics (NP) models can explain this discrepancy, and such NP models are likely to predict deviations of $\\mathcal{B}(K\\to \\pi \\nu \\overline{\\nu})$ from the SM predictions, which can be probed precisely in the near future by NA62 and KOTO experiments. We present correlations between $\\epsilon^{\\prime}_K / \\epsilon_K$ and $\\mathcal{B}(K\\to \\pi \\nu \\overline{\\nu})$ in two types of NP scenarios: a box dominated scenario and a $Z$-penguin dominated one. It is shown that different correlations are predicted and the future precision measurements of $K \\to \\pi \\nu \\overline{\\nu}$ can distinguish both scenarios.",
