Radiative Rare Kaon Decays †

We discuss theoretical issues in radiative rare kaon decays. The interest is twofold: to extract useful short-distance information and understand the underlying dynamics. We emphasize channels where either we can understand non-perturbative aspects of QCD or there is a chance to test the Standard Model.

Rare and Radiative Kaon Decays ∗

We review the status of theory and experiment of very rare and forbidden kaon decays. We then review the radiative non-leptonic decays, and the associated Dalitz pair modes. We pay particular attention to the study of long distance physics in radiative decays within the framework of chiral perturbation theory (χPT). We discuss the experiments that will run in the near future and the modes that ...

Inclusive Rare B Decays

We review the present status of rare B decays, focusing on inclusive decay modes and their role in our search for new physics. We also briefly discuss direct CP violation in rare B decays and the rare kaon decays K → πνν̄ and KL → πνν̄, which offer complementary opportunities for precision flavour physics. Based on invited talks given at the 8th International Conference on Supersymmetries in Phys...

Recent Na48 Results on Semileptonic and Rare Kaon Decays. Measurement of V Us

The new results of investigation of K 0 L e3 and K ± e3 decays performed by NA48 Collaboration are presented. The measured branching fractions are used to extract V us. The values of Ke3 form-factors and radiative K 0 L e3γ branching ratio are reported. A list of recent NA48 results concerning some rare neutral kaon decays is given.

Infnna-iv-2000/4 Radiative Rare Kaon Decays

We review some recent theoretical results on radiative rare kaon decays. Particular attention is devoted to the channels K → πll and K → ππγ, where we are (or might be) able to extract the short distance contributions. This is achieved by a careful study of the long distance part. We study also CP violating observables, which are sensitive also to extensions of the SM. As byproduct, we discuss ...
