Abstract
We report the results of a search for the decay K(L)0 --> pi0pi0gamma conducted by the E799 Collaboration at Fermilab. The amplitude for thi s process vanishes to O(p4) in chiral perturbation theory, so a measur ement of the decay would directly probe O(p) effects. This is the firs t published search for this decay mode and we set a 90% confidence lev el upper limit on the branching ratio of B(K(L)0 --> pi0pi0gamma) < 2. 3 X 10(-4).
