Search of New Physics with Kaon decays at NA 62
نویسنده
چکیده
the current short term phase (data taking completed in years 2007-8) we are studying the ratio RK = Γ(K→eνe(γ)) Γ(K→μνμ (γ)) of leptonic decay rates, which provides a golden probe for testing the structure of the weak interactions. In the second phase (long term) we will then focus on the measurement of the branching ratio of the very rare kaon decay K+ → π+νν̄ aiming at collecting O(100) K+→ π+νν̄ events with 10% background in two years of data taking.

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...
متن کاملFlavor Physics in Kaon Decays
Kaon physics has a glorious history. Parity violation, CP violation, GIM mechanism, CKM mechanism, Determination of Standard Model (SM) parameters, Hadronic physics all have imprints of kaon physics. Kaon physics still plays an important role in particle physics. Some of the main interests today in kaon physics are: The studies of CP violation and rare decays; Determination of SM parameters; Lo...
متن کاملFlavour Physics Beyond the Standard Model: Recent Developments and Future Perspectives
Flavour physics plays a crucial role in the search for physics beyond the Standard Model (SM). While B physics offers many observables to look for deviations from the SM, the highest new physics sensitivity can be obtained in the rare kaon decays K → πνν. Of particular interest are correlations between various flavour violating observables that allow to test the symmetries and the operator stru...
متن کاملNew Physics Search in Flavour Physics ∗ a †
With the running B, kaon and neutrino physics experiments, flavour physics takes centre stage within today’s particle physics. We discuss the opportunities offered by these experiments in our search for new physics beyond the SM and discuss their complementarity to collider physics. We focus on rare B and kaon decays, highlighting specific observables in an exemplary mode. We also comment on th...
متن کاملOverview of Kaon Physics
In this overview, I discuss some of the open issues in Kaon physics. After briefly touching on lattice calculations of Kaon dynamics and tests of CPT, my main focus of attention is on ǫ ′ /ǫ and on constraints on the CKM model. The impact of rare K-decays and of experiments with B-mesons for addressing the issue of CP-violation is also discussed. The importance of looking for signals of flavor-...
