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…
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…
Measurement of the direct emission and interference terms and search for CP violation in the decay K\pm -> π\pmπ^0 g
2 Collaboration
We report on the measurement of the direct emission (DE) and interference (INT) terms of the K\pm -> π\pmπ^0 g decay by the NA48/2 experiment at the CERN SPS. From the data collect…
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
The weak radiative decay Xi0 --> Lambda e+e- has been detected for the first time. We find 412 candidates in the signal region, with an estimated background of 15 +/- 5 events. We…
A precision measurement of direct CP violation in the decay of neutral kaons into two pions
J. R. Batley, NA48 collaboration
The direct CP violation parameter Re(epsilon'/epsilon) has been measured from the decay rates of neutral kaons into two pions using the NA48 detector at the CERN SPS. The 2001 runn…
