Measurement of the decay $K_{L} \to e^{+}e^{-} \gamma \gamma$
The full data set of the NA31 experiment at CERN has been used to analyse the decay mode $K^{0}_{L} \to e^{+}e^{−}\gamma\gamma$. A signal of 47 events has been observed with an estimated background of 6.9 events. The total number of kaon decays in the decay volume was determined to be $(2.1 \pm 0.1_...

| description | The full data set of the NA31 experiment at CERN has been used to analyse the decay mode $K^{0}_{L} \to e^{+}e^{−}\gamma\gamma$. A signal of 47 events has been observed with an estimated background of 6.9 events. The total number of kaon decays in the decay volume was determined to be $(2.1 \pm 0.1_{stat}) \times 10^{9}$. This corresponds to a branching ratio of $8.0 \pm 1.5^{+1.4}_{-1.2} \times 10^{-7}$. |
