The CP violating parameters $\varepsilon$ and $\varepsilon’/\varepsilon$, as well as the branching ratio of the rare decay $K \to \pi \bar{\nu} \nu$ are highly suppressed in the Standard Model and particularly sensitive to flavour violating new physics. In this talk I will discuss the status of the Standard Model prediction of these observables and give an outlook on how to improve the precision of these predictions in the future. The suppression within the standard model implies a sensitivity to loop induced new physics. I will discuss how renormalised results for the one-loop vertex functions can be derived in generic extensions of the standard model that are constrained by perturbative unitarity.
