New final results from an analysis of about 400 K+- --> pi+- gamma gamma rare decay candidates collected by the NA48/2 and NA62 experiments at CERN during low intensity runs with minimum bias trigger configurations are presented. The results include a model-independent decay rate measurement and fits to Chiral Perturbation Theory (ChPT) description. The data support the ChPT prediction for a...

The KLOE experiment at the DAΦNE φ-factory of the INFN Frascati Laboratory collected data corresponding to 2.5 fb^−1 of integrated luminosity.
Neutral kaon pairs produced in φ-meson decays offer unique possibilities to perform tests of fundamental discrete symmetries. The entanglement of the two kaons is exploited to search for possible violation of CPT symmetry and Lorentz invariance in...

Heavy Quarks & Leptons
Kaon decays are a new area of interest at the LHCb experiment. A search for the decay K0S -> mu+ mu- is performed, based on a data sample of 1.0 fb^-1 of pp collisions at sqrt(s) = 7 TeV. The observed number of candidates is consistent with the background-only hypothesis, yielding an upper limit of B(K0S -> mu+ mu-) < 11 (9) x 10^-9 at 95 (90)% confidence level. This limit is a factor of...

Experiment E36 at the Japan Proton Accelerator Research Complex will study the decay of stopped kaons to search for new physics beyond the Standard Model. In particular, the experiment aims to provide the most stringent test of lepton universality to date in a measurement of the ratio of the Ke2 and Kmu2 decay widths, and will simultaneously search for light new particles, such as a heavy...

The rare decays K+ ->π+ ν ν are excellent processes to make tests of new physics at the highest scale complementary to LHC thanks to their theoretically cleaness. The NA62 experiment at CERN SPS aims to collect of the order of 100 events in two years of data taking, keeping the background at the level of 10%. Part of the experimental apparatus has been commissioned during a technical run in...

Recent results and prospects for precision tests of the Standard Model in kaon decay in flight experiments at CERN are presented. A measurement of the ratio of leptonic decay rates of the charged Kaon at a 0.4% precision constrains the parameter space of new physics models with, for example, an extended Higgs sector. Searches for neutrino mass states and the dark photon in the ~100 MeV/c^2...
