The recent release of improved lattice data has revived again the interest on precise theoretical calculations of the direct CP-violation ratio ε /ε. We present a complete update of the Standard Model prediction [1,2], including a new re-analysis of isospin-breaking corrections which are of vital importance in the theoretical determination of this observable. The Standard Model prediction, Re(ε /ε) = (14 ± 5) • 10 −4 , turns out to be in good agreement with the experimental measurement.

“…The main difficulty here is the uncertainty on the SM prediction. The value we report in the table is an educated guess taking into account the recent results in [47][48][49][50]. For a conservative implementation of the present constraint on new physics, we adopt an inflated error covering all available predictions within the 1σ interval.…”

We analyse the sensitivity of quark flavour-changing observables to the MSSM, in a regime of heavy superpartner masses. We analyse four distinct and motivated frameworks characterising the structure of the soft-breaking terms by means of approximate flavour symmetries. We show that a set of six low-energy observables with realistic chances of improvement in the near future, namely ∆M s,d , K , K / K , B(K → πνν), and the phase of D-D mixing, could play a very important role in charactering these frameworks in a regime of superpartner masses up to O(100) TeV. We show that these observables remain very interesting even in a long-term perspective, i.e. even taking into account the direct mass reach of the most ambitious future high-energy colliders. *
