“…The data on CP-averaged Kπ branching ratios can be expressed in terms of three ratios: One should emphasize that in the previous analyses the radiative electromagnetic corrections to charged particles in the final state were not taken into account, as was emphasized in the past (see for example Ref. 104 ). These corrections, worked out in Ref.…”

We report recent progress in SM calculations of b → s transitions. We discuss the first NNLL prediction of theB → Xsγ branching ratio, including important additional subtleties due to nonperturbative corrections and logarithmically-enhanced cut effects, and also recent results on the inclusive modeB → Xsℓ + ℓ − . Moreover, new results on the corresponding exclusive modes are reviewed. Finally, we comment on the present status of the so-called B → Kπ puzzle in hadronic b → s transitions.

We discuss the indirect search for new degrees of freedom beyond the standard model, within flavour physics. In particular, we analyse the minimal flavour violation hypothesis and its phenomenological implications, especially the large-tan beta scenario in supersymmetric models, and also compare it with the constrained minimal flavour violation scenario. Moreover, we briefly discuss some recent progress in inclusive b to s transitions and present a status report of the so-called K-pi puzzle.Comment: 8 pages, 6 figures, based on an invited review talk given at Beauty 2006, the 11th International Conference on B physics at Hadron Colliders, September 2006, Oxford (England

We present an extensive analysis of rare K decays, in particular of the two neutrino modes K + → π + νν and K L → π 0 νν, in the Minimal Supersymmetric extension of the Standard Model. We analyse the expectations for the branching ratios of these modes, both within the restrictive framework of the minimal flavour violation hypothesis and within a more general framework with new sources of flavour-symmetry breaking. In both scenarios, the information that can be extracted from precise measurements of the two neutrino modes turn out to be very useful in restricting the parameter space of the model, even after taking into account the possible information on the mass spectrum derived from high-energy colliders, and the constraints from B-physics experiments. In the presence of new sources of flavour-symmetry breaking, additional significant constraints on the model can be derived also from the two K L → π 0 ℓ + ℓ − modes.
