The search for CP-violating K3 3π0 decay was performed with SND detector at VEPP-2M e+e collider. The total amount of data correspond! ng to 7 million produced K3 mesons was analyzed. No candi date events were found, giving an upper limit of the decay branching ratio: Br(K3 3π0) < 1.4 • 10-5 at 90% confidence level. ©1999 Published by Elsevier Science B.V. All rights reserved.
