The existence of dark matter was suggested, using simple gravitational arguments, seventy
years ago. Although we are now convinced that most of the mass in the Universe is indeed …

We study model-independently the implications of nonstandard scalar and pseudoscalar
interactions for the decays b→ s γ, b→ sg, b→ s l+ l−(l= e, μ) and B s→ μ+ μ−. We find …

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 …

We demonstrate a new source for flavor-changing neutral currents within the minimal
supersymmetric standard model. At moderate to large tan β, it is no longer possible to …

The predictions for the Bs, d–B s, d mixing mass differences ΔMs, d and the branching ratios
Br (B s, d→ μ μ ̄) within the Standard Model (SM) and its extensions suffer from …

We report on a calculation of Higgs-boson contributions to the decays B s→ l+ l− and B→
Kl+ l−(l= e, μ) which are governed by the effective Hamiltonian describing b→ sl+ l …

The present report documents the results of Working Group 2: B, D and K decays, of the
workshop on Flavor in the Era of the LHC, held at CERN from November 2005 through …

The standard model of particle physics describes the fundamental particles and their
interactions via the strong, electromagnetic, and weak forces. It provides precise predictions …

We present an effective Lagrangian formalism for the calculation of flavour changing neutral
and charged scalar currents in weak decays including SU (2)× U (1) symmetry breaking …

The rare decays B→ K (*) l+ l−, B→ K (*) ν ν and B s→ μ+ μ− are analyzed in a generic
scenario where new physics effects enter predominantly via Z penguin contributions. We …
