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...

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...

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....

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.

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...
