Measurement of the decay rate and the parameter $\alpha_{K^{*}}$ of the decay $K_{L} \to \mu \mu \gamma$
The rate of the decay of the neutral K meson into $K_{L}^{0} \to \mu \mu \gamma$ has been measured with the NA48 detector at the CERN SPS. A total of 59 events has been observed with an estimated background of 14 events. The overall Kaon flux was determined to be $1.2 \times 10^{9}$. This observatio...
