Measurement of K^0_e3 form factors
NA48 collaboration
The semileptonic decay of the neutral K meson, KL -> pi e nu (Ke3), was used to study the strangeness-changing weak interaction of hadrons. A sample of 5.6 million reconstructed ev…
Measurement of the branching ratio of the decay KL -> pi e nu and extraction of the CKM parameter |Vus|
NA48 collaboration
We present a new measurement of the branching ratio R of the decay KL -> pi e nu (Ke3), relative to all charged KL decays with two tracks, based on data taken with the NA48 detecto…
Semileptonic KL Decays at NA48
M. Veltri
Preliminary results on KL->pi e nu(gamma) decays collected by the NA48 detector at the CERN SPS are reported. Using a sample of 6.8 X 10^6 reconstructed events BR(Ke3) = 0.4010+-0.…
Search for CP violation in K0 -> 3 pi0 decays
NA48 Collaboration
Using data taken during the year 2000 with the NA48 detector at the CERN SPS, a search for the CP violating decay K_S -> 3 pi0 has been performed. From a fit to the lifetime distri…
