The NA48/2 experiment at CERN reports the first observation of the decay from an exposure of charged kaon decays recorded in $200…
New measurement of the K+- --> pi+-mu+mu- decay
J. R. Batley et al.
A sample of 3120 decay candidates with background contamination has been collected by the NA48/2 experiment at the CERN SPS, allowing a detaile…
Measurements of Charged Kaon Semileptonic Decay Branching Fractions K^+- -> pi^0 mu^+- nu and K+- -> pi^0 e^+- nu and Their Ratio
J. R. Batley, NA48/2 collaboration
Measured ratios of decay rates for Ke3/K2π, K\mu3/K2πand K\mu3/Ke3 are presented. These measurements are based on K^+- decays collected in a dedicated run in 2003 by the NA48/2 exp…
Measurement of the branching ratios of the decays Xi0 --> Sigma+ e- nubar and anti-Xi0 --> anti-Sigma+ e+ nu
I Collaboration
From 56 days of data taking in 2002, the NA48/1 experiment observed 6316 Xi0 --> Sigma+ e- nubar candidates (with the subsequent Sigma+ --> p pi0 decay) and 555 anti-Xi0 --> anti-S…
Search for direct CP-violation in K+- --> pi+-pi0pi0 decays
2 collaboration
A search for direct CP-violation in K+- --> pi+-pi0pi0 decays based on 47.14 million events has been performed by the NA48/2 experiment at the CERN SPS. The asymmetry in the Dalitz…
Observation of a cusp-like structure in the pizero-pizero invariant mass distribution from K+- ==> pi+- pizero pizero decay and determination of the pi-pi scattering lengths
