Measurement of the radiative K-e3 branching ratio

We present a measurement of the relative branching ratio of the decay K0 → π±e±νγ (Ke3γ) with respect to K0 → π±e±ν (Ke3 + K e3γ) decay. The result is based on observation of 19 000 K e3γ and 5.6 × 106 Ke3 decays. The value of the branching ratio is Br(Ke3γ0, E γ* > 30 MeV, θeγ* > 20°)...
