Measurement of the decay rate and form factor parameter $\alpha_{K^{*}}$ in the decay $K_{L} \rightarrow e^{+}e^{-}\gamma$

The decay rate of the neutral K meson $\mathrm{K_{L} \rightarrow e^{+}e^{-}\gamma}$ has been measured with the NA48 detector at the CERN SPS. A total of 6864 events has been observed with an estimated background of 10 events. The branching ratio is $\mathrm{\Gamma(K_{L} \rightarrow e^{+}e^{-}\gamma)...
