Search for the decay KL → π0π0γ

Abstract:
Data from the NA31 experiment at CERN have been used for a search for the decay mode KL → π0π0γ. After all cuts, three events remain in the signal region with an estimated background of 2.2 ± 0.9 events. The upper limit for the branching ratio of KL→π0π0γ is 5.6×10-6 at the 90% confidence level.
