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…
Measurement of K^{0}_{\mu3} form factors
The NA48 Collaboration
This paper reports on a new high precision measurement of the form factors of the K_{L}\to π^{\pm} μ^{\mp} ν_μ decay. The data sample of about 2.3 events was recorde…
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…
Precise measurement of the decay
A. Lai
The decay rate of $\klpgg$ has been measured with the NA48 detector at the CERN SPS. A total of 2558 $\klpgg$ candidates have been observed with a residual background of 3.2%. The…
A precise measurement of the direct CP violation parameter Re(epsilon'/epsilon)
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. With 3.3 mill…
