A comprehensive overview of kaon decays is presented. The standard model predictions
are discussed in detail, covering both the underlying short-distance electroweak dynamics …

In the past decade, one of the major challenges of particle physics has been to gain an in-
depth understanding of the role of quark flavor. In this time frame, measurements and the …

We compute the one-loop matching between the Standard Model Effective Field Theory and
the low-energy effective field theory below the electroweak scale, where the heavy gauge …

These lectures describe in detail the effective Hamiltonians for weak decays of mesons
constructed by means of the operator product expansion and the renormalization group …

A bstract The angle γ of the standard CKM unitarity triangle can be determined from B→ DK
decays with a very small irreducible theoretical error, which is only due to second order …

We make the simple observation that there exists a universal unitarity triangle for all models,
like the SM, the Two Higgs Doublet Models I and II and the MSSM with minimal flavour …

We revisit the issue of the limit on the scale of left-right symmetry breaking. We focus on the
minimal SU (2) L× SU (2) R× U (1) BL gauge theory with the seesaw mechanism and …

We report on a new approach to a global CKM matrix analysis taking into account most
recent experimental and theoretical results. The statistical framework (R fit) developed in this …

Abstract The Standard Model (SM) does not contain by definition any new physics (NP)
contributions to any observable but contains four CKM parameters which are not predicted …

The mixing of the known quarks with new heavy singlets can modify significantly some
observables with respect to the standard model predictions. We analyze the range of …
