First Observation and Measurement of the Decay K+- -> pi+- e+ e- gamma

2 Collaboration, J. R. Batley

Using the full data set of the NA48/2 experiment, the decay K+- -> pi+- e+ e- gamma is observed for the first time, selecting 120 candidates with 7.3 +- 1.7 estimated background ev…

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 $\times 1 0^{6}$ events was recorde…

Determination of the branching ratios $Γ (K_{L} \to 3 π^{0}) /Γ (K_{L} \to π^{+} π^{-} π^{0})$ and $Γ (K_{L} \to 3 π^{0}) /Γ (K_{L} \to π e ν)$

Improved branching ratios were measured for the $K_{L} \to 3 π^{0}$ decay in a neutral beam at the CERN SPS with the NA31 detector: $Γ(K_L \to 3 π^0) / Γ(K_L \to π^+ π^- π^0) = 1.611…

Measurement of K^{0}_{\mu3} form factors

Determination of the branching ratios Γ(KL​→3π0)/Γ(KL​→π+π−π0) and Γ(KL​→3π0)/Γ(KL​→πeν)

Determination of the branching ratios $Γ (K_{L} \to 3 π^{0}) /Γ (K_{L} \to π^{+} π^{-} π^{0})$ and $Γ (K_{L} \to 3 π^{0}) /Γ (K_{L} \to π e ν)$
