oral

Measurement of the helicity suppressed ratio of charged kaon leptonic decay rates BR(K --> e nu)/BR(K --> mu nu) has long been considered as an excellent test of lepton universality and the Standard Model (SM) description of weak interactions. It was realised recently that the suppression of the SM contribution might enhance the sensitivity to SUSY-induced effects to an experimentally...

41. Status and prospects for the Ke2/Kmu2 at KLOE/KLOE2

I would propose to present and discuss at HQL10 about the prospects for improving the constraints on lepton-flavor violation in MSSM with the KLOE-2 experiment. KLOE has recently published the analysis on the Ke2 decays: http://dx.doi.org/10.1140/epjc/10052-009-1177.x and the KLOE-2 physics programme has been published on http://dx.doi.org/10.1140/epjc/10052-010-1351.1

The measurement of the S-wave pi pi scattering lengths is a fundamental test of the validity of Chiral Perturbation Theory. We report on the final NA48/2 result, which uses the complete NA48/2 data set with more than a million reconstructed K+-e4 decays. From these events we have determined the decay form factors and pi pi scattering lengths a0_0 and a2_0. The result is the most precise...

6. Precision measurements of kaon radiative decays in NA48

We report our final result on the measurement of direct photon emission (DE) in the decay K+- -> pi+- pi0 gamma and its interference (INT) with the inner bremsstrahlung amplitude. For this measurement the full NA48/2 data set with about 600k reconstructed K+- -> pi+- pi0 gamma decays was analyzed, which is factor of 30 larger than for previous experiments and a factor of three w.r.t....

7. The NA62 experiment at CERN

oral

The NA62 experiment aims to collect of the order of 100 K+ to pi+ nu nubar decays with a 10% level of background. Studies using Monte Carlo simulation of the apparatus and data from test beam runs were performed to assess the expected sensitivity of the apparatus. The results about signal acceptance and background rejection will be presented.

9. Measuring KS and KL lifetimes at KLOE

Kaons

oral

A phi-factory offers the possibility to select pure kaon beams: neutral kaons from phi → KSKL are in fact produced in pairs and the detection of a KS (KL) tags the presence of a KL (KS). This allows to perform precise measurement of kaon properties. We are presently finalizing new determinations of the KL and KS lifetimes using the whole KLOE data set, consisting of more than 109 phi...
