我们讨论对Kaon混合参数$ \ VAREPSILON_K $的新物理学（NP）贡献，直接cp违规参数$ \ varepsilon^\ prime/\ prime/\ varepsilon $ of $ k \toππ$，以及稀有的衰减，稀有S} \至μ^+μ^ - 在一般两个Higgs Doublet模型的上下文中。 We focus on contributions of top quark related exotic couplings, and show that simultaneous presence of flavor conserving and flavor violating interactions can lead to large NP effects in kaon sector, while being consistent with the stringent constraints from B physics observables such as $B_{s(d)}$-$\bar B_{s(d)}$ mixing, $B_s\to μ^+ μ^-$,和$ b \ tosγ$。我们强调$ \ varepsilon_k $，$ k^+\ toπ^+ν\barν$和$ b_s \ toμ^+μ^ - $之间相关性的重要性。
We discuss new physics (NP) contributions to kaon mixing parameter $\varepsilon_K$, direct CP violation parameter $\varepsilon^\prime/\varepsilon$ of $K\to ππ$, and rare decays $K^+\to π^+ν\barν$, $K_L\to π^0ν\barν$ and $K_{L, S}\to μ^+ μ^- $ in the context of general two Higgs doublet model. We focus on contributions of top quark related exotic couplings, and show that simultaneous presence of flavor conserving and flavor violating interactions can lead to large NP effects in kaon sector, while being consistent with the stringent constraints from B physics observables such as $B_{s(d)}$-$\bar B_{s(d)}$ mixing, $B_s\to μ^+ μ^-$, and $b\to sγ$. We stress on the importance of correlations between $\varepsilon_K$, $K^+\to π^+ν\barν$ and $B_s\to μ^+ μ^-$ that can be exploited to distinguish the parameter space corresponding to a light (sub-TeV) or heavy (TeV) scale charged Higgs boson.
