First observation and study of the decay
2 Collaboration, J. R. Batley, G. Kalmus +121
The NA48/2 experiment at CERN reports the first observation of the decay based on a sample of 2437 candidates with 15% background contam…
Search for Heavy Neutrinos in Decays
The NA62 Collaboration
The NA62 experiment recorded a large sample of decays in 2007. A peak search has been performed in the reconstructed missing mass spectrum. In the absence…
Searches for Lepton Number Violation and Resonances in Decays
2 collaboration
The NA48/2 experiment at CERN collected a large sample of charged kaon decays to final states with multiple charged particles in 2003--2004. A new upper limit on the rate of the le…
ChPT tests at the NA48 and NA62 experiments at CERN
NA48/2, NA62 Collaborations, : +159
The NA48/2 Collaboration at CERN has accumulated unprecedented statistics of rare kaon decays in the Ke4 modes: Ke4(+-) () and Ke4(00) ($K^\pm \to π^0 π^…
Recent NA48/2 and NA62 results
F. Ambrosino, A. Antonelli, G. Anzivino +156
The NA48/2 Collaboration at CERN has accumulated and analysed unprecedented statistics of rare kaon decays in the modes: () and $K_…
Measurement of the branching ratio of the decay
J. R. Batley, G. E. Kalmus, C. Lazzeroni +110
From the 2002 data taking with a neutral kaon beam extracted from the CERN-SPS, the NA48/1 experiment observed 97 candidates with a backgroun…
New Precise Measurements of the $\xilamgam$ and $\xisiggam$ Decay Asymmetries
J. R. Batley
The decay asymmetries of the weak radiative Hyperon decays Xi0 \to Lambda gamma and Xi0 \to Sigma0 gamma have been measured with high precision using data of the NA48/1 experiment…
Empirical parameterization of the K+- -> pi+- pi0 pi0 decay Dalitz plot
J. R. Batley, A. J. Culling, G. Kalmus +118
As first observed by the NA48/2 experiment at the CERN SPS, the $\p0p0$ invariant mass (M00) distribution from $\kcnn$ decay shows a cusp-like anomaly at M00=2m+, where m+ is the c…
Determination of the S-wave pi pi scattering lengths from a study of K+- -> pi+- pi0 pi0 decays
2 Collaboration
We report the results from a study of the full sample of ~ 6.031 10^7 K+- -> pi+- pi0 pi0 decays recorded by the NA48/2 experiment at the CERN SPS. As first observed in this experi…
Precise measurement of the K+- --> pi+-e+e- decay
2 collaboration
A sample of 7253 decay candidates with 1.0% background contamination has been collected by the NA48/2 experiment at the CERN SPS, allowing a precise measu…
First observation and branching fraction and decay parameter measurements of the weak radiative decay Xi0 --> Lambda e+e-
NA48 Collaboration
