SEARCH FOR THE DECAY K-L-]3-GAMMA

Abstract:
Data from the NA31 experiment at the CERN SPS have been used for the first search for the decay mode KL → 3γ. Seven events have been found with an estimated background of 6.7 ± 1.5 events. The corresponding upper limit for the branching ratio is Γ(KL → 3γ) Γ(KL → all) = 2.4 × 10-7 at the 90% confidence level, assuming a phase-space decay distribution. © 1995.
