Observation of the decay mode K0L-->γγee
Abstract
Results of a search for the decay mode K0L-->γγee (K0L-->γee with a hard internal bremsstrahlung) are reported. The measured branching ratio is (6.6+/-3.2)×10-7, in agreement with the QED prediction of 5.8×10-7. The infrared cutoff for both branching ratios is the requirement that both photons have an energy of at least 5 MeV in the center of mass.
