SUMMARY:CP violation and rare Kaon decays in the Standard Model and beyond

DESCRIPTION: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 part
 icularly sensitive to flavour violating new physics. In this talk I will d
 iscuss the status of the Standard Model prediction of these observables an
 d give an outlook on how to improve the precision of these predictions in 
 the future. The suppression within the standard model implies a sensitivit
 y 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.
